Python download, installation, uninstallation and visualization tools for Windows system

The first step is to download Python

Enter Python official website

1. Click Downloads to enter the Downloads page

2. On the Download page, scroll down to the Release list, select the version you want to download, and click the Download button at the back.

I chose python3.10.0

3. Select the corresponding system type and click to enter the download queue.

This is a Windows 11 64-bit system

Step 2. Install Python

1. Double-click the exe file, check Add Python 3.10 to PATH, and select custom installation

2. PIP (Python Package Manager) must be checked and click Next

3. You must check Add Python to environment variables to add Python to the environment variables, and then select the installation path of Python.

It is best to name it Python + version number. Example: Python3.10, (note that the package name should not contain Chinese, spaces, or special characters, otherwise there may be many incomprehensible problems in the future because of the package name)

4. On the installation success page, you must check disable path length limit, and then close

Disabling the system's automatic path length limit can save us a lot of trouble.

5. Check whether the installation is successful

Check the python version command: python --version
Check the python package management tool version command: pip --version

6. Start python and exit from the command line

Enter python in the command line to start python, which can be encoded.
Enter exit or use the quit() function to exit python. The

installed python is an interpreter, which is translated line by line into machine language for execution.
Automatically modify the configuration file. Download the pip package management tool from Douban.
pip config set global.index-url https://pypi.doubanio.com/simple

Step 3. Uninstall Python

1. Find Python related programs through Control Panel-Programs and Functions

2. Uninstall Python3.10.0 first, then uninstall Python Launcher

3. Delete the entire Python installation directory

4. Delete the corresponding Python environment variable

Right-click My Computer, Properties, select Advanced System Settings, click Environment Variables, and delete the path related to Python in the Path path.

Step 4. Install the Python visualization tool PyCharm

1. Enter the official website of jetbrians

2. Select Developer Tools —> PyCharm

3. Click the Download button on the PyCharm page to enter the download page.

4. Select the corresponding system (Window), Community version, and click to download.

There is a fee for the professional version, but there is a one-month trial period, and the community version is free to use.

Click on the downloaded PyCharm, keep Next, and install it.
