Case insensitive argparse choices

Question

Is it possible to check argparse choices in case-insensitive manner?

import argparse
choices = [\"win64\", \"win32\"]
parser = argparse.ArgumentParser()
pars         


        

Answer 1

Keeping the case information would also be possible with a one liner:

type = lambda arg: {x.lower(): x for x in choices}[arg.lower()],

Where choices would be the same list as passed to the choices parameter.
