…d_argument (pythonGH-13805) 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: ```python parser = argparse.ArgumentParser() parser.add_argument('-x', type=argparse.FileType) ``` https://bugs.python.org/issue37150 (cherry picked from commit 03d5831) Co-authored-by: zygocephalus <[email protected]>
