New submission from Demid <[email protected]>:
There is a possibility that someone (like me) accidentally will omit
parentheses with FileType arguments after FileType, and parser will contain
wrong file until someone will try to use it.
Example:
parser = argparse.ArgumentParser()
parser.add_argument('-x', type=argparse.FileType)
