Take a look at the "Talking to the User" topic in my tutorial(link below)

About 3/4 way down there is a section "Command Line Parameters"

that describes how to do what you want.


Or read the documentation on sys.stdin

You can't easily run scripts at the interactive prompt (ie >>>). You can
import a module and if your script is written such that you can execute
it by calling a function then that's the simplest option.

This usually means having your script code look like:


######## MyModule.py ######

import sys

def something:....

def another......

def main(arg):

      # my main code here

if __name__ == "__main__":

      args = sys.argv

      main(args[1])

####################


Then you


>>> import MyModule

>>> MyModule.main(myArg)
