Call .py file with arguments

Technical Topics PyScript

When using <py-script src="/myscript.py"></py-script> I would like to call it with arguments since myscript.py can be called from the command line like myscript.py arg1 arg2.
How can I envoke this in pyscript? <py-script src="/myscript.py arg1 arg2"></py-script> doesn’t work.

I don’t believe there is a direct way to do this in PyScript currently - the src attribute of a PyScript tag fetches the content from the specified URL as the Python code to be run. It doesn’t know how to accept additional arguments.

You could potentially open an issue/proposal about it over on GitHub, I don’t think I’ve seen this suggested before. Might stir some interesting discussion.

If refactoring your code just a bit is acceptable, a workaround is to wrap your code in a function:

def main(arg1, arg2):
    #Original here

if __name__ == "__main__":
    main(sys.argv[1], sys.argv[2])

And then in PyScript:

#py-env fetches myscript.py and loads it into the virtual filesystem
<py-env>
    - paths:
        - ./myscript.py
<py-env>
<py-script>
    from myscript import main
    main(arg1, arg2)
</py-script>

This should preserve the ability to use the script from the command line, while also allowing you to feed arguments to the main function directly.

Great, I can refactor the myscript.py to fit both. Thanks!
