If you want to run a .py python file from command line and you also want to pass the argument using command line you can use argparse library.
This can be done as below:
import argparse # Command Line arguments argp = argparse.ArgumentParser() argp.add_argument('--my_var', dest="my_var", action="store", type=int, default=5) params = argp.parse_args() myvar= params.my_var print(myvar)

I learned how to use Apple's Emoji thanks to a fellow Recurser who shared her Weather Program code with me:

I also get Argparse now & learned about Apple's Extensible Keyboard Shortcuts!!
All because I got to listen to a friend be enthusiastic about her code!!
Using argparse
One use of argparse in Python that I use often is writing a script that takes an input from the command line. This way, you can run the script iteratively over multiple files.ย
import argparse parser = argparse.ArgumentParser() parser.add_argument(โ--infโ) args = parser.parse_args() data = np.loadtxt(args.inf)
