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

Transform the argument into lowercase by using

type = str.lower

for the -p switch.

This solution was pointed out by chepner in a comment. The solution I proposed earlier was

type = lambda s : s.lower()

which is also valid, but it's simpler to just use str.lower.
