System environment:

Because of the cross-platform of the Python language, the system of the code is no different from the system type and platform, and people think it is convenient to use Windows.

Win10

Note the point:

When Windows installs python3.0, pay attention to the use of custom installation, do not use the default installation, so you can choose to add python environment variables to their system environment variables, avoid manually adding environment variables,

Otherwise, you cannot find Python's environment variables when using Windows cmd with Python.

Setting Environment variables manually

My Computer right-click Advanced System Settings Advanced "Environment variable" system variable "path, in the existing variable path; +python installation path

If you have multiple versions of Python installed, it is recommended that you copy a different version, rename it, and avoid duplication.
