Python 3.9 introduced new operators for dictionary merging. You'll learn more about making alloys from your `dicts` by reading the original PEP-0584. [PEP-0584 simplifies dictionary operations](https://peps.python.org/pep-0584/), enhancing Python's ease of use and readability.. 

# Quiz

Which one of these code samples correctly demonstrates the use of Python's dictionary merging as guided by PEP 584?

# Sample 1
```python
dict1 = {'a': 1, 'b': 2}
dict2 = {'b': 3, 'c': 4}
merged_dict = dict1 | dict2
```

# Sample 2
```python
dict1 = {'a': 1, 'b': 2}
dict2 = {'b': 3, 'c': 4}
merged_dict = dict1 + dict2
```

Post your answer in the comments! 0 if you think that Sample 1 is correct, 1 otherwise. As usually, the correct answer will be explained in the first comment.

What is NFT Trading Cards
Published: 2023-11-06 06:33:59

Trading NFT (Non-Fungible Token) cards refers to the practice of buying, selling, or exchanging digital collectible cards that are represented as [NFTs](https://cryptobulls.biz/blog/who-are-the-rising-nft-artists/) on blockchain technology. NFTs are unique digital assets that are indivisible and have proven ownership and authenticity, making them ideal for representing collectibles like trading cards.

## Here's how trading NFT cards typically work:

Creation: Artists or creators design and mint NFT cards on blockchain platforms, such as Ethereum, Binance Smart Chain, or others. Each card is assigned a unique token ID, making it one-of-a-kind.

Ownership: Once minted, these NFT cards can be owned by individuals, and ownership is recorded on the blockchain, ensuring the card's provenance.

Trading: Owners can trade or sell their NFT cards on various NFT marketplaces. These marketplaces serve as platforms where users can list their cards for sale, set prices, and engage in transactions with other collectors.

Scarcity and Rarity: NFT cards often have limited editions, which can make certain cards more valuable due to their scarcity and rarity. Some cards are part of series or collections, and collectors seek to complete these sets.

Authenticity and Provenance: NFTs provide a transparent and immutable record of ownership, ensuring the authenticity and history of each card. This provenance is crucial in the world of collectibles, as it helps verify the card's origin and ownership history.

Utility and Interoperability: Some NFT cards are designed for use in specific blockchain-based games or applications. They can have in-game value or utility, making them more attractive to collectors.

Secondary Market: The secondary market for NFT cards is where most trading occurs. Buyers and sellers negotiate prices, and transactions are executed through smart contracts, ensuring a secure and transparent exchange.

Wallets: To trade NFT cards, collectors need a digital wallet that supports the blockchain on which the NFTs are created. These wallets store and manage the NFTs, and the private keys are used to access and control them.

Trading NFT cards has gained significant popularity in recent years, and some NFT cards have fetched high prices in auctions and private sales, often driven by the demand of collectors and enthusiasts. It's important to research and understand the specific NFT card market and the blockchain it's built on before getting involved in trading to ensure a safe and informed experience.

Clarifying the often-confused terms in data engineering: **upstream** refers to the processes or data sources that provide data to a particular process, while **downstream** refers to the processes or systems that consume data from a particular process.

![Upstream and downstream](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/1mpd0nleke2onxajbq1c.jpg)

For example, if you have a data pipeline that collects data from multiple sources, cleans and transforms it, and then loads it into a database, the sources of the data are upstream, and the database is downstream.

Upstream processes usually have a significant impact on downstream processes, as the quality and reliability of data they provide affect the quality and reliability of downstream data. Therefore, it is important to ensure that upstream processes are well-designed and well-maintained to prevent downstream issues.

Similarly, downstream processes can also impact upstream processes. For instance, if a downstream process fails to consume data correctly or in a timely manner, it can cause bottlenecks or even data loss upstream. Therefore, both upstream and downstream processes need to be monitored and optimized to ensure the overall success of the data pipeline.

C# - Struct Improvements in C# 10.0
Tags: csharp, programming, tutorial, beginners
Published: 2023-12-02 15:30:00

C# 10.0 brought several improvements to structs, enhancing their functionality and making them more flexible for various use cases. One significant enhancement is the ability to declare parameterless constructors and field initializers in structs.

Here's how to utilize these struct improvements:

1. **Parameterless Constructors in Structs:**
   You can now define a parameterless constructor in a struct. This allows for more control over how struct instances are initialized, especially when used with collections or serialization frameworks.

2. **Field Initializers in Structs:**
   Similar to classes, C# 10.0 structures allow field initializers. This means you can assign default values to fields directly in their declaration.

Example:

```csharp
public struct Point
{
    public double X { get; set; }
    public double Y { get; set; }

    // Parameterless constructor
    public Point()
    {
        X = 0;
        Y = 0;
    }

    public Point(double x, double y)
    {
        X = x;
        Y = y;
    }
}

public static void Main()
{
    var defaultPoint = new Point(); // Calls parameterless constructor
    var customPoint = new Point(5.0, 10.0);

    Console.WriteLine($"Default Point: ({defaultPoint.X}, {defaultPoint.Y})");
    Console.WriteLine($"Custom Point: ({customPoint.X}, {customPoint.Y})");
}
```

In this example, the `Point` struct includes a parameterless constructor, allowing you to create a `Point` with default values without having to provide specific arguments. This makes structs more versatile and user-friendly, especially when you need to ensure a certain state upon initialization.

These improvements make structs more like classes in terms of their capabilities, offering more flexibility in designing your data structures while still allowing you to benefit from the value-type semantics of structs.
面子与傻逼的关系
Published: 2023-12-02 15:07:09

- 一个人一旦追求了面子， 那么就容易丧失追求真理的路线；

- 这很难做到两者兼顾，因为人的注意力资源有限，你在一个方向上分配了一定的单位，就一定会在另一个方向上损失一定的单位；

- 在追求面子上投入了一定的注意力资源，那么必然导致追求真理的注意力资源被剥夺，就容易把人往傻逼的方向上拽；

- 面子分为几种：
	1、追求荣誉是一般的追求社会认同的心理；
	2、好面子是低等追求社会认同的心理；
	3、虚荣心是低等中的下贱级别的追求社会认同心理；

- 越是好面子的人，越是傻逼，傻逼程度与好面子程度呈正相关；

- 好面子的人不但傻逼，而且懦弱；因为内心强大的人：“我的规矩就是规矩”，完全不在乎你们怎么看（你们的认同）；

- 对面子毫不在乎的人，更有可能纯粹、简单、实在；

- 在真理和社会认同面前你只有一个选择，不选面子的人不一定会去追求真理而变得聪明，而选择面子一定会变得傻逼；
How to Create a CLI App in 5 Steps
Published: 2023-11-30 05:25:21

In Phase 3 of my learning journey at Flatiron, we began to learn about Python. As we approach the end of this phase, our project of the phase was to create a CLI app. Our group decided to make a Fitness Tracker CLI, and here's a five-step skeleton of how we did it! 

Step 1 - Plan
Before beginning to plan, we set clear goals for what we wanted to accomplish. We value the gym, so we wanted to create an app that allowed users to add or remove exercises and workouts. 

Step 2 - Data Models
After deciding what we wanted our app to do, we needed to decide what classes we would add and what their relationships would be. We agreed on our project's three classes (exercise, workout, and user). For their relationships, we wanted "workout" to have a one-to-many relationship with "exercise" and "workout" to belong to a user.

Step 3 - ORM
During this step, we used SQLAlchemy to interact with our database. During this step, we created modules for the ORM methods we wanted.

STEP 4 - CLI
After setting up SQLAlchemy and our ORM, we focused on creating the CLI. To help with this process, we used Click to generate the command-line interface (CLI). At this point, we also defined our commands for the CLI. 

Step 5 - Implementing CLI Commands
Here, we wrote functions for our CLI commands and added information for error messages. We also used this step to implement PrettyTable, Figlet, and animations as embellishments to our CLI app to give it some more pizzazz. 

Overall, it was a fun experience to create our first CLI app!
