- When writing Python scripts, be sure to add this!
- People who use Python often write some scripts. Whether it is to improve work efficiency or to meet some specific needs, Python scripts are a common and useful thing. However, I recently discovered a problem that I had never noticed before, which is whether to add if __name__ == "__main__": This statement in the script actually has a great impact on the use of the script, and there is a lot of knowledge in it. . Common Misunderstandings: Many friends are more casual when writing scripts. Simple scripts are written down directly without functions and executed sequentially. For more complex scripts, functions may be added. This way of writing is less readable and often makes people unable to find it at a glance.

- The best combination for writing Python code on Windows!
- How to do Python development on Windows? Should I use a plain text editor like the masters do, or should I use a more complete IDE? Should I use the built-in command line tool, or do I need to install a new Terminal? This article will show you how to use MS Terminal and VS Code officially maintained by Microsoft to protect Python development. One of the great benefits of using Windows is that it has so many applications, and even a powerful GPU can do other "work" in your free time.

Let’s talk about it one by one: Constructor The constructor of all classes in Python is __init__. According to our needs, the constructor is divided into parameterized constructor and parameterless constructor. If there is no constructor defined currently, the system will automatically generate an empty constructor with no parameters. For example: when there is an inheritance relationship
