Message 182449 - Python tracker (original) (raw)

3.2 has a better error message:

"{:<06}".format(Decimal("1.2")) Traceback (most recent call last): File "", line 1, in File "/usr/lib/python3.2/decimal.py", line 3632, in format spec = _parse_format_specifier(specifier, _localeconv=_localeconv) File "/usr/lib/python3.2/decimal.py", line 5600, in _parse_format_specifier "format specifier: " + format_spec) ValueError: Alignment conflicts with '0' in format specifier: <06

That's because '0' already has a special meaning:

"Preceding the width field by a zero ('0') character enables sign-aware zero-padding for numeric types. This is equivalent to a fill character of '0' with an alignment type of '='."
