One nice aspect of this suggestion is that supplying the comma would map directly to the "grouping" parameter in https://docs.python.org/3/library/locale.html#locale.format: >>> import locale >>> locale.setlocale(locale.LC_ALL, "en_IN.utf8") 'en_IN.utf8' >>> locale.format("%d", 10e9, grouping=True) '10,00,00,00,000' Cheers, Nick. -- Nick Coghlan | ncogh...@gmail.com | Brisbane, Australia _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
