Simple and easy-to-understand pip domestic source configuration tutorial, allowing you to get started quickly, you need specific code examples

[Foreword]
Pip is a package management tool for Python , which can help us easily install, upgrade and manage Python packages. However, when domestic users use Pip, due to well-known reasons, they may encounter problems such as slow download speeds and connection timeouts. In order to solve these problems, we can configure the domestic Pip source to improve download speed and stability.

[Step 1: Back up the original configuration file]
Before starting the configuration, we first need to back up the original Pip configuration file so that it can be restored to its original state in case of problems. Open a terminal or command prompt window and execute the following command:

cp ~/.pip/pip.conf ~/.pip/pip.conf.bak

This command will back up the original Pip configuration file pip.conf.

[Step 2: Create a new configuration file]
Execute the following command to create a new Pip configuration file pip.conf:

touch ~/.pip/pip.conf

[Step 3: Edit the configuration file]
Use any text editor, open the pip.conf file, and enter the following:

[global]

pip uninstall package_name

4. View installed Package list:
