There are a few doubts that I may want to clarify as of now. Thanks a lot for the link @Yichao, @Josef.
1. The function definition in python is def main(argv). I wrote function main(args) in the Julia equivalent. Is this the right way to do it? 2. For the line in Python args = parser.parse_args(), the Jullia equivalent is args = parse_args(s) and correct me if I am wrong. This function is mapping the command line arguments to a dictionary with keys 3. This is the most confusing part for me. I really don't get the Julia equivalent of these two lines. if __name__ == "__main__": main(sys.argv[1:]) Could you please clarify my questions?
