This article mainly introduces how to use the click tool in Python, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand it.

First, get started quickly

The command line uses to dynamically pass values at run time to make the program do what it wants to do. Now there is a very simple program:

If you use the command line, you can do dynamic assignment by entering the parameter 10 on the command line. Something like this:

You just need to modify the original code:

Note:-- times is consistent with the parameter times, otherwise an error will be reported.

After adding these two lines, you can use help information and parameters.

Run python loops.py-- help:

Run python loops.py-- times 3:

Install_requires, required dependencies

Py_modules, required module

Entry_points, indicating the entry function of the script

Run hello yuz directly on the command line after configuration.
