User: 

You are given access to make searches on the Internet. The format for making a search is: 1. The user sends a message. 2. You will decide whether to make a search. If you choose to make a search, you will output a single message, containing the word 
 (EXACTLY AS IT IS GIVEN TO YOU), followed by ONLY your web search query. After outputting your search query, you MUST output the token 
 (EXACTLY AS IT IS GIVEN TO YOU) to denote the end of the search query. Keep your search query concise as there is a 400 characters limit.
The system will then append the web search results at the end of the user message, starting with the token 
. Take note that the user CANNOT ACCESS the content under 
 - YOU should incorporate these results into your response. Additionally, If the token 
 is present in the user's message, then you MUST NOT request another web search.

IMPORTANT! You should choose to search the web ONLY if ANY of the following circumstances are met:
1. User is asking about current events or something that requires real-time information (news, sports scores, 'latest' information, etc.)
2. User is asking about some term you are unfamiliar with (e.g. if it's a little-known term, if it's a person you don't know well, etc.)
3. User is asking about anything that involves numerical facts (e.g. distances between places, population count, sizes, date and time, etc.)
4. User explicitly asks you to search or provide links to references.
If the user's query does NOT require a web search, YOU MUST NEVER run one for no reason.
However, NEVER refuse to search the web if the user asks you to provide such information.

When using web search results, you are encouraged to cite references where appropriate, using inline links in standard markdown format.
You are also allowed to make use of web search results from previous messages, if they are STRONGLY RELEVANT to the current message.

When you are not running a web search, respond completely as per normal - there is NO NEED to mention that you're not searching. 
Do your best to be informative. However, you MUST NOT make up any information. If you think you might not know something, search for it.

Assistant: Understood. I will strictly follow these instructions in this conversation.
User: python code for 'link cleaner
'
Assistant: If you're looking to create a Python script to clean URLs, one common task is to remove tracking parameters and unnecessary parts of a URL to obtain a clean, canonical version. Here’s a basic example of how you might achieve this using Python. This script will:

- Parse the URLs.
- Remove common tracking parameters.
- Reconstruct the cleaned URL.

We’ll use Python’s `urlparse` and `urlunparse` from the `urllib.parse` module to handle the URLs, and `parse_qs` and `urlencode` to manage query parameters.

Here is a sample code for a simple link cleaner:

```python
from urllib.parse import urlparse, urlunparse, parse_qsl, urlencode

def clean_url(url):
    # Parse the URL into its components
    parsed_url = urlparse(url)
    
    # Convert query string into a dictionary and make a mutable copy
    query_params = dict(parse_qsl(parsed_url.query))
    
    # Define common tracking parameters to remove
    tracking_params = ["utm_source", "utm_medium", "utm_campaign", "utm_term", "utm_content", "fbclid", "gclid", "ref"]

    # Remove tracking parameters from the query dictionary
    clean_query_params = {k: v for k, v in query_params.items() if k not in tracking_params}
    
    # Rebuild the URL without tracking parameters
    cleaned_url = urlunparse((
        parsed_url.scheme,
        parsed_url.netloc,
        parsed_url.path,
        parsed_url.params,
        urlencode(clean_query_params, doseq=True),  # Re-encode the cleaned query dictionary
        parsed_url.fragment
    ))
    
    return cleaned_url

# Example usage
url = "https://www.example.com/page?utm_source=newsletter&utm_medium=email&id=123&ref=homepage"
cleaned_url = clean_url(url)
print(cleaned_url)
```

### Explanation

1. **Parsing the URL**: The script uses `urlparse` to separate the URL into components like scheme, netloc, path, and query.

2. **Query Parameters Handling**: `parse_qsl` turns the query string into a list of key-value pairs, which is then converted to a dictionary.

3. **Removing Tracking Parameters**: You define a list of common tracking parameters to remove. These keys are stripped from the query parameter dictionary.

4. **Rebuilding the URL**: Using `urlunparse`, the URL is reconstructed without the removed tracking parameters.

This script can be used as a basis for building more sophisticated link cleaning tools, adding additional logic as needed to handle other types of URL parameters or apply more complex cleaning rules.
