New submission from Serhiy Storchaka: Berker suggested to move this part from issue30152 to its own PR.
When the file can be imported as a module and run as a script it is worth to make command-line parsing modules (getopt, optparse, argparse) be imported only when they are used, i.e. when the file is ran as a script. Most of the stdlib modules already do this. Proposed patch moves imports of command-line parsing modules and some other modules used only when the module is ran to the main() function or to the branch executed only if __name__ == "__main__". It doesn't change scripts and files that are purposed to be used only for running (__main__.py, main.py). ---------- components: Library (Lib) messages: 292319 nosy: serhiy.storchaka priority: normal severity: normal stage: patch review status: open title: Import command-line parsing modules only when needed type: enhancement versions: Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30166> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
