New submission from Serhiy Storchaka <storchaka+cpyt...@gmail.com>:
The C implementation supports both formats "n" and "N". The Python implementation only supports format "n". >>> from decimal import Decimal >>> format(Decimal('1e100'), 'n') '1e+100' >>> format(Decimal('1e100'), 'N') '1E+100' >>> from _pydecimal import Decimal >>> format(Decimal('1e100'), 'n') '1e+100' >>> format(Decimal('1e100'), 'N') Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/serhiy/py/cpython/Lib/_pydecimal.py", line 3766, in __format__ spec = _parse_format_specifier(specifier, _localeconv=_localeconv) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/serhiy/py/cpython/Lib/_pydecimal.py", line 6194, in _parse_format_specifier raise ValueError("Invalid format specifier: " + format_spec) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ValueError: Invalid format specifier: N ---------- components: Library (Lib) messages: 405861 nosy: facundobatista, mark.dickinson, rhettinger, serhiy.storchaka priority: normal severity: normal status: open title: The Python implementation of Decimal does not support the "N" format type: behavior versions: Python 3.10, Python 3.11, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45739> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
