How to pass arguments from command line to a main function in python

Question

I've been doing some exercises for AI course and I to get arguments to my code directly from the command line, for example python solution.py resolution_examples/small_example.txt. I now in java you can pass arguments to main fun via command line, but can you do the same thing in python?

sys module has attribute argv which contains all command line parameters.

import sys
print(sys.argv)

For fast handling, that should be enough but when you need a bit more control over cli parsing, standard library has lib called argparse: https://docs.python.org/3/library/argparse.html
