1 Introduction

Little Diaosi : Brother Yu, the song that has become more popular recently, why bother.
Xiaoyu : Then you can become a VIP.
Little Diaosi : Just kidding, my money is not blown by the wind.
Xiaoyu : Then what are you doing, you still want to prostitute for nothing?
Little Diaosi : (⊙o⊙)... Sure enough, Brother Yu understands me.
Xiaoyu : ...No, no, we must support genuine copyright.
Little Diaosi : I didn't say I don't support copyright.
Xiaoyu : Then you still want to whore for nothing?
Xiao Diaosi : I just thought about changing the way to support copyright.
Xiaoyu : I'll go, don't lie to me.
Little Diaosi : Really, I think Brother Yu can think of it.
Xiaoyu : I... can't think of it.
Little Diaosi : Don't make trouble. And what you can't think of, you treat me like a child.
Xiaoyu : Hehe.

Little Diaosi : Brother Yu, tell me quickly what's going on.
Xiaoyu : I'll only tell you one person, you can't spread it outside.
Little Diaosi : It is necessary.

2. Code combat

2.1 Ideas

Because the player needs to be generated and the downloaded music needs to be played automatically. so:

First: the computer disk needs to have enough space;
Second: you need to install some third-party libraries,
Third: GUI realizes downloading music to a specified folder.
Fourth: drinking Ace of Spades, listening to downloaded songs.

2.2 Installation

A third-party library is required here, as follows:

requests
PySimpleGUI
retrying

Here, I see that it can be installed one by one or in batches.
I only show the installation of the PySimpleGUI library.

pip install PySimpleGUI

For other installation methods, you can refer to these two articles:

After the installation is complete, you can write code.
