[New-bugs-announce] [issue27941] Bad error message from Decimal('garbage') across the py3 range

[Samuele Santi]

New submission from Samuele Santi:

Looks like, on some occasions, running ``Decimal('garbage')`` on Python 3.x decimal raises this error:

    decimal.InvalidOperation: [<class 'decimal.ConversionSyntax'>]

instead of the usual:

    decimal.InvalidOperation: Invalid literal for Decimal: 'garbage'


This seems to be caused by the built-in decimal module on 3.x, while it's just fine with decimal.py / _pydecimal.py (eg. the system Python on Archlinux).

I'm attaching the output from a few tests I made against different interpreters.
