Анализ логических значений с помощью argparse
I would like to use argparse to parse boolean command-line arguments written as "--foo True" or "--foo False". For example:
my_program --my_boolean_flag False However, the following test code does not do what I would like:
import argparse parser = argparse.ArgumentParser(description="My parser") parser.add_argument("--my_bool", type=bool) cmd_line = ["--my_bool", "False"] parsed_args = parser.parse(cmd_line) Sadly, parsed_args.my_bool evaluates to True. This is the case even when I change cmd_line to be ["--my_bool", ""], which is surprising, since bool("") evalutates to False.
How can I get argparse to parse "False", "F", and their lower-case variants to be False?
