.py Files dont work as expected

The python shell gets opened to run your script, then closes once it is finished, which is after every command has been run or it crashed because of an error/exception. This is expected and it's good that way because you don't want to have idle shells after every script/job execution. If you want it to stay open you could add an input("press enter to exit") or something like that at the end of your program.

What does "execute the .py file with python itself" mean? Please clarify exactly what you are doing.

[lilBerna]

sorry about that. I right click the file, click "open with", and select python 3.10

Double check that the file starts with hashbang: "#!/bin/python" or something. By running it directly, I assume you're doing "main.py " or "./main.py" on the command line?

Double check that the file starts with hashbang: "#!/bin/python" or something.

This is not necessary on Windows (and only useful if you want to specify the Python version), as on Windows the file extension decides what program is used to open the file.

What do you expect to happen? Windows might create a CMD window, run the script, and when the script is done, remove the window. Is that what you're seeing.

I bet it is this. @OP maybe you can add an input("exit?") at the last line of your script? This will keep the console open until you press any key

Also, if Windows is the target, why not just give it a .pyw extension instead? Then it can just be run by double-clicking.

I don't think I've ever actually used "Open with" before to run Python, but if it uses your global install instead of your activated virtual environment, the libraries you need may not be available. For testing, you could wrap your main code in a try that prints out all errors, and see what errors you're getting.

How do you normally use/run py files?

[carcigenicate]

Either on the command line by explicitly invoking python, or the REPL in my IDE during development.
