I'm not sure... Well, it's not so clear which strings are accepted previously (i.e. what's was documented). PEP 515 claims one. The docs says something different: ---->8--- If value is a string, it should conform to the decimal numeric string syntax after leading and trailing whitespace characters, as well as underscores throughout, are removed ---->8------- and --->8------ Underscores are allowed for grouping, _as with integral and floating-point literals in code_. -->8------- The 1-st sentence doesn't specify the way underscores are removed. And given the 2-nd sentence: it's clearly can't be like the current behaviour of the Decimal constructor. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44267> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
