[issue28612] str.translate needs a mapping example
Gaurav Tatke added the comment: Hi, Pardon my ignorance, I am new to this but have below queries/thoughts - 1. Why would we say that adding new keys during lookup phase is an unpleasant side-effect? From what I understood by docs, one of the main reasons to use defaultdicts is to be able to insert a missing key and give a default value to it. 'defaultdict' doc itself suggest that doing this is cleaner and faster than using dict.setdefault(). 2. I believe defaultdict perfectly fits in this context of creating translation table for str.translate(). Even if we have very large string containing all characters from 4-5 languages, our defaultdict will still be comparatively small. It is easier to create a translation table using defaultdict when we have to strip most characters out of a string as in the example requested in the issue. Creating a translation table using str.maketrans() or by user defined function is tricky in this use case. 3. If argument for using defaultdict in this context is not convincing, shall I just give a patch, giving example of str.translate() using str.maketranse()?

[issue21150] Add quick links table to argparse docs
Gaurav Tatke added the comment: Hello All, I would like to help with this issue. I am a beginner. I am attaching a 'SampleOfSummaryTable.PNG' file which I think is one way of organizing summary table. I think if we put quick links of function parameters in summary table then it will make existing parameter quick links above detailed summary of each parameter as redundant. Please let me know if this is okay. -- nosy: +Gaurav Tatke Added file: http://bugs.python.org/file45972/SampleOfSummaryTable.PNG ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21150> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
