This is the full error: Traceback (most recent call last): File "ansi.py", line 49, in args = Parser.parse_args() NameError: name 'Parser' is not defined

First, you need to create a parser.

parser = argparse.ArgumentParser()

Then you need to call it's parse_args method.

args = parser.parse_args()
