New submission from retnikt <retn...@gmail.com>:
In the library documentation for argparse, the section for ArgumentParser.add_subparsers ( https://docs.python.org/3/library/argparse.html#sub-commands ) states that there is a parameter for 'action' with the description 'the basic type of action to be taken when this argument is encountered at the command line'. However, no such parameter actually exists, and passing it to the function causes very strange behaviour: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python3.6/argparse.py", line 1716, in add_subparsers action = parsers_class(option_strings=[], **kwargs) TypeError: __init__() got an unexpected keyword argument 'parser_class' This line should be removed from the documentation. It is present in versions 3.4+ and 2.7 ---------- assignee: docs@python components: Documentation messages: 348718 nosy: docs@python, retnikt priority: normal severity: normal status: open title: argparse subcommand docs has non-existent parameter "action" type: behavior versions: Python 2.7, Python 3.5, Python 3.6, Python 3.7, Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37717> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
