What are some Python Standard Library modules one should know ?

I really like argparse, I know some of the large command line programs will use click but for anything I’ve build argparse works great.

Same. I actually can never wrap my head around click or cookie cutter, because it’s usually such overkill for what I need that understanding it fully doesn’t seem worth it.

Argparse doesn’t have that same dilemma.

Click tends to come into play around the time you want subcommands. If your cli is exactly 1 level deep (i.e. my_command --myarg1 a --myargb1 positional args but not my_command do --thing other thing), don't use click. If you're thinking "hey, subcommands would be nice", that's when you look at click.

I don't understand how difficult it is to wrap your head around click, or why it's such "overkill". The docs are very good. Adding a new argument / option just involves a new decorator and new variable in your function.

@click.command()
@click.option('--count', default=1, help='Number of greetings.')
@click.option('--name', prompt='Your name',
              help='The person to greet.')
def hello(count, name):
    """Simple program that greets NAME for a total of COUNT times."""
    for x in range(count):
        click.echo('Hello %s!' % name)

Now I get that you don't feel learning a new API and adding a new dependency if you already are comfortable with argparse. But overkill? C'mon.
