The specific explanations of the 5 options checked in the above figure are as follows:
This step is mainly to install the basic functions and help documents of the Python interpreter. We only need to check all of them by default and click "Next" directly.
Step4: Advanced option settings
Enter the advanced options dialog box. This step is mainly used to install compilation and debugging related functions, including adding environment variables and associated Python files, etc., check as shown in the figure, and you can modify the installation path (you can set the path by yourself).
Step5: Installation

Click "OK" to start the command line window, enter "Python" in the window, and press the <Enter> key. If the message shown in the figure below appears, the installation is successful.
The information in the above figure includes the installed Python version, the release time of the version, the type of installation package, etc. This information will be different due to the different versions selected. When the command prompt changes to ">>>", the installation is successful and it is waiting for the user to input Python commands.
This is the end of the Python interpreter installation tutorial for beginners. Is your Python interpreter installed?
