Answer 1

According to your second picture, select 从已知列表中选择安装程序.默认的话,安装程序目录在C:/用户/username(你的)/Appdata/Local/programs/python/python.exe and choose which program you want. If not, find the program path name and set it yourself.

or from cmd进入程序所在目录,参考CMD命令进入某个目录,执行python hello.py.

If it cannot be opened by double-clicking, it means that the default opening program is not set. Set it to python to open it for execution, or set it to open it as an editor

Answer 3

Python’s bin directory is not added to the environment variable
