New submission from John Parejko:
As described in PEP-3127, the "leading-zeros" formatting for octal was removed
from python 3. This is a good thing(tm), but the recommendation of that PEP to
improve the error message of the raised exception[1] was apparently never
implemented. I just ran into this while with some recently-ported python2 code,
and it took a while to figure out the problem.
Although this is going to be less of a problem with time as people convert to
pure python3, it will be very helpful during the transition period.
