What can Python do?

It can do daily tasks, such as automatically backing up your MP3, and can make websites. Many famous websites like Zhihu and YouTube are written in Python. It can be the background of online games, and the background of many online games is developed in Python.

None of the above has ever happened, hahaha. But I do know that Python can do some interesting things, such as copying Douyin with Pycham, which is also widely used for Python development. Turtle is a Python library for drawing simple minions, roses, love trees, and so on. This library can also be said to be a magic pen of Ma Liang.

1, create a game screen 2, load title 3, load button, 4, when the mouse over ‘forget it’ reload desktop and randomly generate a ‘forget it’ coordinates; 5. Display different titles when the mouse cursor moves over ‘ok’. Here is the Python script:

Over 100 lines of Python code and the Tkinter library, we end up with the following effect:

This is just a simple version, but as you get more familiar with Tkinter, you can add more beautiful background photos and make your code explode even more beautifully for you!

Will, will, will, and that’s it. Now you’re ready to surprise your girlfriend with your Python boyfriend charm. I’ve always thought that having a Boyfriend who knows Python is particularly handsome and attractive when typing code.
