Powershell and cmd don't run my Python (. py) files

Question

Hi, people, I hope that you are fine, I'm trying to run my Python (. py) files in Powershell and CMD using windows 10, I've already reinstalled Python three times and put the checkmark on the PATH part, i don't know exactly how, when or where I'm F up things but those files simply are not running, I saved the files on my Desktop with the .py extension, then I go to Powershell or Command Prompt and type md desktop, and try to run the file and nothing, when I type python in PS or CMD inside the terminal and run commands (inside them) are working without issues, I was reading some articles regarding the PATH, but I don't want to screw things on my computer, one error is "[Errno 22] Invalid argument".
Thanks in advance, any help or assistance will be more than welcome.

Answer 1

i use vs code and i use an easy way to compile my programs, try searching for code runner extension on vs code. you won't have to touch the terminal everytime you compile.
another easy way to compile python is to simply write python / python3 on the terminal then drag the python file into the terminal. it wil automatically show the full directory and you can run it instantly.

Answer 2

Ive tried and failed many times. I ended up making a batch file with a couple lines to run it. Just open a text file and type:
c:\python27(or_whatever)\python.exe
c:\path_to\somescript.py %*
#add next line if its a program that just shows
#output once
@pause
Then save the text file with a .bat extesnsion.
when you double click it will run the script

Answer 3

Yeah no worries.
The first line is the full path to your python.exe
the second line is the full path to your script AND %* after a space
@pause goes in when you have a super simple program that just prints out the solution to an equation or some other one step process. it just pauses the screen so you can see the output. otherwise the window would just automatically close
I would just find then in file explorer and copy paste the paths

they may be running a different os

Thank you, it can be done in Powershell as well or only in CMD?
I've put on CMD as an admin:
C:\WINDOWS\system32> where python
Then it shows this:
C:\Users\MyName\AppData\Local\Programs\Python\Python38\python.exe
and
C:\Users\MyName\AppData\Local\Microsoft\WindowsApps\python.exe
It returns those two lines together, I don't know what to do now, sorry.

🤦🏾‍♂️, well thank you once again.
Ok, first at all, you are saying that I have two Pythons installed in the AppData folder and both should be removed from my laptop by using Control Panel and add/remove programs and then reinstall Python using Administrator rights,
I'm not sure how to install with administrator rights, so it has to be downloaded from windows store or python.org?
Then you said to clean the path environment variables and reboot before reinstalling and use "run as administrator" when I run the setup program and install to C:\Python38, sorry I didn't get that either.
Whenever you have time, please, verify my question.

Martin Taylor
Yes, you're right! I've one year learning Python and of course more about Windows, my solution on Powershell was to cd my user folder then cd Desktop and then the folder where I have the VS code
.py files and then run the desired script
, I know that is not the correct approach, but is working so far, thank you very much for your assistance, and yes it's again in AppData folder, 🤣

Martin Taylor
Thank you, man!
Yes, I will stay away from Powershell
, I will keep using the cmd better, I will try to learn more about System Admin in Windows and Linux, very useful commands you sent me,
This " cd %USERPROFILE% or cd %userprofile%" has to be typed with the "%"? and by userprofile you mean that specific word or my name?

Answer 9

Try Git Bash

It is the latest one, Python 3.8 something, thanks

Thanks man! Sorry, would you say that again but slowly, please?
Text file(I'm assuming notepad or something like that),
c:\python27(in my case I think is python38), maybe
So it's "c:\python38\python. exe" right?
Then
c:\path_to\somescript.py %*
☝🏾In that same way or do I need to change something?
Then
Add next line if it's a program that jusg shows output once
@pause
☝🏾 Where that "@pause" goes?
Thanks in advance!

Sorry, what was that again, I didn't get it?
The most frustrating thing is that you see people online on tutorials, etc., and their .py scripts run just fine in the different terminals, 🤔🤣
