if name == “main”:
scraper = WebNovelScraper()
scraper.scrape_web_novel()
The provided code is designed to scrape web novels from given URLs, specifically it seems tailored for a site that might have a pattern like “https://bednovel.com/bednovel/{novel-name}/ch{chapter-number}”. Here is an overview of how the code works and potential enhancements or corrections:

1. Initialization (__init__):
- Initializes an instance variable filter_terms which can be used to exclude paragraphs containing specific terms during the scraping process. However, its implementation is not complete as there is no interface to populate this list from user input or otherwise.

2. User Input (get_input):
- A generic method to retrieve user input, with error handling for type conversion. This is used for getting URLs and corresponding chapter ranges.

3. Chapter Input (get_chapter_input):
- Retrieves user input for the URLs of the web novels to be scraped and the chapter ranges (start and end) for each. It asks for ending chapters only, with starting chapters hardcoded as [1], which could be seen as a limitation.

4. Constructing Chapter URLs (get_chapter_url):
- Generates chapter URLs using a preset pattern. This method lacks flexibility for websites that don’t follow this URL structure.

5. Scraping Chapter Information (scrape_chapter_info):
- Fetches and parses the webpage to retrieve the chapter title. Error handling is included for network issues and HTML parsing errors.

6. Fetch Paragraphs (fetch_paragraphs):
- Similarly retrieves the content of a chapter, looking specifically for paragraph (&lt;p&gt;) elements. No content filtering is applied at this stage.

7. Saving Chapter Content (save_chapter_to_document):
- Writes the chapter title and its content (paragraphs) into a Microsoft Word document object.

8. Saving Chapters for Given Ranges (save_chapters_for_ranges):
- Manages document creation and saving for given chapter ranges of a novel. It loops through the chapter range, scrapes content, and applies filtering based on filter_terms before saving to a .docx file.

9. Scrape Web Novel (scrape_web_novel):
- Orchestrates the retrieval of URLs and their chapter ranges, and initiates the scraping and saving process for each.

10. Main Execution Block:
- Creates an instance of WebNovelScraper and calls scrape_web_novel, kicking off the process.

### Potential Corrections and Enhancements:
- Chapter Start Input: The code does not ask for a starting chapter, defaulting to 1. It would be beneficial to allow users to specify both start and end chapters.
- Filter Terms Usage: While filter_terms is initialized, there’s no mechanism in place for the user to define these terms. Implementing such a feature could improve content customization.
- Flexibility in URL Construction: The get_chapter_url assumes a specific URL pattern. It might not work for all sites; allowing user input for URL patterns could be more useful.
- Error Handling in Document Saving: More robust error handling (e.g., for permission issues or disk space constraints) during document saving could improve reliability.
- User Interface Improvements: Implementing a graphical user interface or a more interactive command-line interface could improve usability.
- Concurrency for Improved Performance: Introducing concurrency (e.g., using threading or asyncio) could significantly reduce the time required to scrape novels with many chapters.

In summary, while the script is a good starting point for web scraping of novel content, there is potential for it to become more user-friendly, flexible, and efficient with some enhancements.


Create a function that checks if the folder with the required document is available. If it is present, proceed to the next input. The script needs to run in a loop until all the inputs, including the URL and the end chapter number, are exhausted. After each iteration, delete the used URL and end chapter and start afresh with a new URL and end chapter.

to run this script in Hugging Face and save all the docx files in a Python database. Before running the script, it needs to check if the required file is present or not.
To modify the provided code to include a loop that checks if a folder with a required document exists, and if so, proceeds to the next input while running in a continuous loop until all inputs are exhausted, we need to perform several tasks. Additionally, we’ll account for deleting used URLs and end chapters after each iteration and starting afresh with new input.

However, please note that integrating directly with a “Python database” as mentioned would require more specific details about what you mean by that. For the sake of generality and the focus on loop and input handling enhancements as requested, let’s focus on these aspects. Storing files in a database typically involves saving either the file path or the file content in a blob column in databases like SQLite or similar actions in other types of databases.

Given these requirements and clarifications, let’s adjust the WebNovelScraper class accordingly:

1. Modify Initialization Method: Add a method to check for the existence of folders/documents and reset inputs.
2. Enhance Looping Logic: Adjust how the loop iterates through URLs and chapter ranges.

Here’s a condensed version with the key modifications:

import os
import requests
from bs4 import BeautifulSoup
from docx import Document

class WebNovelScraper:
    def init(self):
        self.filter_terms = []
        self.base_folder_path = os.path.join(os.path.dirname(os.path.abspath(file)), “novels”)

    def folder_check(self, folder_name):
        “”“Check if a folder for the novel exists”“”
        path = os.path.join(self.base_folder_path, folder_name)
        return os.path.exists(path)

    def get_chapter_input(self):
        while True:
            url = input("Enter URL of the web novel (or ‘done’ to exit): “).strip()
            if url.lower() == “done”:
                break
                
            # Folder check based on URL to keep unique
            folder_name = url.replace(” “, “-”).lower()
            if self.folder_check(folder_name):
                print(“This URL has already been processed.”)
                continue

            start_chapter = int(input(“Enter starting chapter number: “).strip())
            end_chapter = int(input(“Enter ending chapter number: “).strip())
            
            # Assume URL cleanup and modification logic here
            cleaned_url = url.lower().replace(” “, “-”)
            
            self.save_chapters_for_range(folder_name, cleaned_url, start_chapter, end_chapter)

    def save_chapters_for_range(self, folder_name, url, start_chapter, end_chapter):
        document = Document()
        for chapter in range(start_chapter, end_chapter + 1):
            # Your scraping and saving logic…
            print(f"Processing chapter {chapter} for {url}…”) # Placeholder for actual scraping and saving logic

        # Example save path setup
        save_path = os.path.join(self.base_folder_path, folder_name, f”{url}.docx”)
        os.makedirs(os.path.dirname(save_path), exist_ok=True) # Create directory if it does not exist
        try:
            document.save(save_path)
            print(f"Chapters saved in {save_path}.”)
        except Exception as e:
            print(f"Error saving document: {e}”)

    def run(self):
        if not os.path.exists(self.base_folder_path):
            os.makedirs(self.base_folder_path)
        self.get_chapter_input()

if name == “main”:
    scraper = WebNovelScraper()
    scraper.run()


### What’s Changed or Enhanced:
- folder_check Method: Checks the existence of a folder based on the provided name.
- get_chapter_input Loop: Modified to continually ask for URLs and chapter ranges, checks if a folder for the novel exists, and skips if it does.
- Novels Base Folder: Introduced a base folder (novels) to organize novel documents.
- Unique Folder per Novel: Assuming each URL is for a different novel, each novel gets its folder based on its URL to avoid overwriting old files.
- Graceful Exiting: Allows for an exit from the input loop with “done”.

Regarding your requirement to run the script on Hugging Face and save all .docx files in a Python database, running this script as is would require an environment capable of executing Python scripts and using external libraries (requests, beautifulsoup4, python-docx). Saving to a Python database would depend on the specific database technology you’re using. If by “Python database” you meant a simple file-based database like SQLite, integrating saving logic would involve writing additional code to interface with the database API, insert the file content or paths, and manage retrieval.
make that url and end chapter are provied in the script itself sepered by comma
If you want the URLs and end chapters to be provided directly in the script, separated by commas, you’ll need to adjust the WebNovelScraper class to accept this structure. Instead of dynamically obtaining this information through user input in a loop, you’ll be statically defining them. Here’s how you could modify the existing code to use a predefined list of tuples, each containing a URL and the corresponding end chapter. Each tuple could represent a novel and its chapter range. For simplicity, we’ll assume each novel download starts from chapter 1, as your original requirements seem to indicate a static starting point. If a different starting chapter is needed, you could easily adjust the tuple structure to include this information as well.

Let’s modify the main parts of the script to accommodate these changes:

import os
import requests
from bs4 import BeautifulSoup
from docx import Document

class WebNovelScraper:
    def init(self, novels_info):
        self.novels_info = novels_info
        self.base_folder_path = os.path.join(os.path.dirname(os.path.abspath(file)), “novels”)
        self.filter_terms = []

    def folder_check(self, folder_name):
        “”“Check if a folder for the novel exists.”“”
        path = os.path.join(self.base_folder_path, folder_name)
        return os.path.exists(path)

    def save_chapters_for_range(self, folder_name, url, start_chapter, end_chapter):
        document = Document()
        for chapter in range(start_chapter, end_chapter + 1):
            chapter_url = self.get_chapter_url(url, chapter)
            # Your scraping and saving logic…
            print(f"Processing chapter {chapter} for {url}…“)  # Placeholder

        save_path = os.path.join(self.base_folder_path, folder_name, f”{url}.docx")
        os.makedirs(os.path.dirname(save_path), exist_ok=True)
        try:
            document.save(save_path)
            print(f"Chapters saved in {save_path}.“)
        except Exception as e:
            print(f"Error saving document: {e}”)

    def get_chapter_url(self, url, chapter):
        # Construct the chapter URL here based on your URL pattern
        pass

    def run(self):
        if not os.path.exists(self.base_folder_path):
            os.makedirs(self.base_folder_path)
        
        for novel_info in self.novels_info:
            url, end_chapter = novel_info
            folder_name = url.replace(" “, “-”).lower()
            if self.folder_check(folder_name):
                print(f"This URL {url} has already been processed.”)
                continue
            self.save_chapters_for_range(folder_name, url, 1, end_chapter)

if name == “main”:
    # Define your novels URLs and their corresponding end chapters here
    novels_info = [
        (“example-novel-url-1”, 50),
        (“example-novel-url-2”, 100)
    ]
    
    scraper = WebNovelScraper(novels_info)
    scraper.run()


### Changes Made:
- The __init__ method now takes novels_info, a list of tuples. Each tuple should contain a URL and the corresponding end chapter number for a novel.
- Removed methods for interactive input (get_input, get_chapter_input) since this version defines novels and chapters directly in the code.
- Modified the run method to iterate over the provided list of novels and their end chapters (novels_info), processing each without asking for user input.
- Added a placeholder comment in get_chapter_url; you should implement the logic to construct chapter URLs based on your website’s structure.
- The script now checks if a folder for the novel already exists and skips processing if so.

This approach should suit your need to define URLs and end chapters directly in the script, separating each novel and its chapter range with commas within the novels_info list. Remember to replace "example-novel-url-1", "example-novel-url-2", and the chapter numbers with the actual URLs and chapters you wish to scrape.
also add an function that if only network connection is avalaible then only loop will run
To ensure the script only attempts to scrape web novels when a network connection is available, you can integrate a simple function that checks for internet connectivity before proceeding with the main loop. We’ll use a commonly accessible website like “http://www.google.com” for this purpose as a connectivity check; however, you can substitute it with any reliable website that you expect to be always online.

Below is how you can incorporate the internet connection check into the WebNovelScraper class:

import requests
from bs4 import BeautifulSoup
from docx import Document
import os
import socket

class WebNovelScraper:
    def init(self, novels_info):
        self.novels_info = novels_info
        self.base_folder_path = os.path.join(os.path.dirname(os.path.abspath(file)), “novels”)
        self.filter_terms = []
        
    def check_internet_connection(self, host=“http://www.google.com”, timeout=5):
        “”“Check if the internet connection is available.”“”
        try:
            requests.head(host, timeout=timeout)
            return True
        except (requests.ConnectionError, requests.Timeout, socket.gaierror):
            return False
        
    def folder_check(self, folder_name):
        “”“Check if a folder for the novel exists.”“”
        path = os.path.join(self.base_folder_path, folder_name)
        return os.path.exists(path)

    def save_chapters_for_range(self, folder_name, url, start_chapter, end_chapter):
        document = Document()
        for chapter in range(start_chapter, end_chapter + 1):
            chapter_url = self.get_chapter_url(url, chapter)
            # Your scraping and saving logic…
            print(f"Processing chapter {chapter} for {url}…“)  # Placeholder

        save_path = os.path.join(self.base_folder_path, folder_name, f”{url}.docx")
        os.makedirs(os.path.dirname(save_path), exist_ok=True)
        try:
            document.save(save_path)
            print(f"Chapters saved in {save_path}.“)
        except Exception as e:
            print(f"Error saving document: {e}”)

    def get_chapter_url(self, url, chapter):
        “”“Construct the chapter URL.”“”
        return f"https://example.com/{url}/chapter-{chapter}"  # Adjust based on the actual pattern

    def run(self):
        if not self.check_internet_connection():
            print(“No internet connection detected. Please check your network and try again.”)
            return
        
        if not os.path.exists(self.base_folder_path):
            os.makedirs(self.base_folder_path)
        
        for novel_info in self.novels_info:
            url, end_chapter = novel_info
            folder_name = url.replace(" “, “-”).lower()
            if self.folder_check(folder_name):
                print(f"This URL {url} has already been processed.”)
                continue
            self.save_chapters_for_range(folder_name, url.lower().replace(" ", “-”), 1, end_chapter)

if name == “main”:
    # Define your novels URLs and their corresponding end chapters here
    novels_info = [
        (“example-novel-url-1”, 50),
        (“example-novel-url-2”, 100),
        # Add more as needed
    ]
    
    scraper = WebNovelScraper(novels_info)
    scraper.run()


### Key Addition:

- check_internet_connection Function: This function attempts to make a HEAD request to “http://www.google.com”. If the request succeeds or times out, it assumes an internet connection is available and returns True. If it catches an exception indicative of network issues, it returns False. This approach is generally reliable for most use cases, though it assumes that Google’s homepage is always accessible (replace the URL as appropriate for your situation).

By incorporating this connectivity check at the start of the run method, the script ensures that it only proceeds with web scraping if an internet connection is available, adhering to the requirement for network connectivity before operation.
make it that all urls in passes to single varible and also end chapters
If you prefer to have all URLs and their corresponding end chapters passed as individual lists into a single variable for simplicity, you can structure your script to accept these inputs and then pair them together internally. This approach allows you to maintain a clear and straightforward interface for defining novels to be scraped.

Here’s how you can modify the WebNovelScraper class to take separate lists of URLs and end chapters combined into a single variable (for example, as a dictionary) and then process them accordingly:

import requests
from bs4 import BeautifulSoup
from docx import Document
import os

class WebNovelScraper:
    def init(self, novels_config):
        self.urls = novels_config[‘urls’]
        self.end_chapters = novels_config[‘end_chapters’]
        self.base_folder_path = os.path.join(os.path.dirname(os.path.abspath(file)), “novels”)
        self.filter_terms = []
        
    def check_internet_connection(self, host=“http://www.google.com”, timeout=5):
        “”“Check if the internet connection is available.”“”
        try:
            requests.head(host, timeout=timeout)
            return True
        except requests.RequestException:
            return False

    def folder_check(self, folder_name):
        “”“Check if a folder for the novel exists.”“”
        path = os.path.join(self.base_folder_path, folder_name)
        return os.path.exists(path)

    def save_chapters_for_range(self, folder_name, url, start_chapter, end_chapter):
        “”“Placeholder for your scraping and saving logic”“”
        print(f"Processing {folder_name} from chapter {start_chapter} to {end_chapter}…“)
        
        # Document creation and save logic should be here
        # …
        
        print(f"Chapters for {folder_name} have been processed.”)

    def run(self):
        if not self.check_internet_connection():
            print(“No internet connection detected. Please check your network and try again.”)
            return
        
        if not os.path.exists(self.base_folder_path):
            os.makedirs(self.base_folder_path)
        
        for url, end_chapter in zip(self.urls, self.end_chapters):
            folder_name = url.replace(" “, “-”).lower()
            if self.folder_check(folder_name):
                print(f"This URL {url} has already been processed.”)
                continue
            self.save_chapters_for_range(folder_name, url.lower().replace(" ", “-”), 1, end_chapter)

if name == “main”:
    novels_config = {
        ‘urls’: [“example-novel-url-1”, “example-novel-url-2”],
        ‘end_chapters’: [50, 100]
    }
    
    scraper = WebNovelScraper(novels_config)
    scraper.run()


### Key Changes:
- Initialization: Instead of directly receiving a list of tuples, the __init__ method now expects a dictionary (novels_config) with two keys: 'urls' and 'end_chapters', each containing a list of URLs and their corresponding last chapters to be scraped.
- run Method: Iterates over the lists of URLs and end chapters simultaneously using zip to pair each URL with its corresponding end chapter. This ensures the scraper processes each novel up to the specified chapter.

This approach simplifies the external interface for defining novels and chapters, making it easier to add or remove novels from the scraping queue by updating the novels_config variable. It maintains the internal logic’s flexibility while presenting a cleaner external configuration structure.
save the ouput docs file in an database
To save the output .docx files into a database, you will need to select the type of database you want to use. For this example, I’ll demonstrate how to save the .docx document files into a SQLite database using Python, as SQLite is lightweight and does not require a separate server to operate, making it an excellent choice for demonstration purposes.

Please note that storing large binary files (like .docx files) in a database is generally not recommended for production environments due to potential performance issues. Instead, it’s typical to save files on disk or in a blob storage service and store the path or URL to the file in the database. However, for small-scale applications, educational purposes, or where needed, here’s how you can do it:

1. Install Required Packages: Ensure you have the necessary packages installed. You’ll need sqlite3 (which is included with Python’s standard library) and other packages used in previous examples.

2. Create a Database and Table: You’ll create a simple database and table to store your documents.

3. Modify the Saving Logic: Instead of saving to the filesystem, you’ll save the document’s binary data directly into the database.

Here’s an example of how you
