: They told me about this experiment. I'll learn who you are only from the first comment you leave. Hello unknown. Bob : Hi Bob. I don't think we know each other. I'm in the New Zealand office, Auckland to be precise. Alice : That's quite a timezone difference. I'm on the other side of the Earth, I just checked. Bob : Bom dia in Lisbon! Correct? Time passes and we haven't written a single line of code. I start Alice def main(): pass : Let's make it a console app Bob import argparse def main(): parser = argparse.ArgumentParser(description="TBD") args = parser.parse_args() : TBD? Come on.

How about this?
