[Python-Dev] base64 module

Hello, base64 module documentation for b64decode function says, "TypeError is raised if s were incorrectly padded or if there are non-alphabet characters present in the string." But this doesn't seem to be the case. Testcase: import base64 base64.b64decode('%') Since % is a non-alphabet character, this should raise TypeError (btw, shouldn't this be ValueError instead?), but Python 2.4.3 silently ignores. I found this while experimenting with IronPython. IronPython 1.0 Beta 5 gives: Traceback (most recent call last): File base64, line unknown, in b64decode SystemError: cannot decode byte: '%' It's not TypeError, but it doesn't silently ignore either.
