Python optparse from method call?

Question

I have two python scripts with the following structure:

# Script1.py
from optparse import OptionParser
def main():
    parser = OptionParser()
    parser.add_option("-a", "--add-foobar", action="store_true", help="set foobar true",
        dest="foobar", default=False)
    options, args = parser.parse_args()
    print options.foobar

if __name__ == "__main__":
    main()

# Script2.py
from Script1 import main as script1Main
def main():
    script1Main()

Is there a way to pass command line arguments from script 2 to script 1? Script 1 in this example is immutable, therefore this must be done only thorough optparse.

I'm confused...how are you calling the scripts and why are you doing it this way? Why do you say that Script 1 is "immutable?" — Adam Smith, May 20 '15 at 21:49
Both of these scripts have the executable bit set. They would be run in the command line (For example, *./Script1.py -a* or *./Script2.py*). Script 1 is immutable as in I cannot change the code in script 1. As to the why, that's a very good question! :D — Alexander, May 20 '15 at 21:52

If you don't pass any arguments to parse_args, it just uses the value of sys.argv[1:], which is going to be whatever arguments were passed when you called Script2.py. The fact that Script2.py calls Script1.main doesn't change that.

Firstly, maybe use argparse instead. You can process all arguments in script 2, then pass the argument handle to script 1.

# Script1.py
def main(args):
    print args

# Script2.py
import argparse
from Script1 import main as script1Main

def main():
    parser = argparse.ArgumentParser(
    parser.add_option("-a", "--add-foobar", action="store_true", help="set foobar true", default=False)
    args = parser.parse_args()
    script1Main(args)

if __name__ == "__main__":
    main()
