如何使Python 3.9运行命令提示符windows 10？

Question

"python --version Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Manage App Execution Aliases."

This is what I get trying to make sure it works (clearly it doesn't). I'm quite a rookie with all this. I started cause I wanted to run some script on bluestacks, so I needed Python and ADB added both PATH. The problem comes here.... It is indeed added to Path:

C:\windows\system32;C:\windows;C:\windows\System32\Wbem;C:\windows\System32\WindowsPowerShell\v1.0\;C:\windows\System32\OpenSSH\;C:\Users\Sierra\AppData\Local\Microsoft\WindowsApps;C:\platform-tools;C:\Users\Sierra\AppData\Local\Programs\Python\Python39;C:\Users\Sierra\AppData\Local\Programs\Python\Python39\Lib;

This is PATHEXT: .COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC

This is PYTHONPATH (I made it since I saw someone saying it would fix it):

C:\Users\Sierra\AppData\Local\Programs\Python\Python39;C:\Users\Sierra\AppData\Local\Programs\Python\Python39\Lib;C:\Users\Sierra\AppData\Local\Programs\Python\Python39\include;C:\Users\Sierra\AppData\Local\Programs\Python\Python39\DLLS;C:\Users\Sierra\AppData\Local\Programs\Python\Python39\Scripts;C:\Users\Sierra\AppData\Local\Programs\Python\Python39\Lib\site-packages

Weird enough the fact that ADB works fine:

C:\Users\Sierra>adb --version Android Debug Bridge version 1.0.41 Version 30.0.5-6877874 Installed as C:\platform-tools\adb.exe

Since I did the same in both cases, I can't get why it's not working. Maybe I did something wrong with the Python version I downloaded? Weird thing too, since I also have stilled version 3.8

Also, the script I need says "Python 3.7.X installed and added to PATH." I guessed 3.9 would work, since it's the newest

I apoloogize cause my English. I'm not native speaker, so I could have messed up somewhere. Many thanks,! Forgot to tell, I use Windows 10

When you run the setup exe for python a list of tiny boxes should pop up and one will say add PATH to python? If you click yes it will add PATH to python which seems like your issue I think? If you have multiple versions of python installed that could cause a issue type python in cmd if it has a error then you didn't install python properly. Double check you have all the required modules installed if that doesn't work then I'm lost. Anyways here's the code to open cmd.

import os

os.system("cmd")
