Note that this is a regression relative to 2.6, where the same call returns '' (which is different from what it returns on linux, where the result would be '%f', or OSX, where the result would be 'f'). (Tests done on windows XP using pythons installed from the python.org installers.)
My guess is that the difference between python 2.6 and python 2.7+ is issue 4804. I'm therefore adding the nosy list from that issue to this one.
For the OP's benefit: my guess is that this is a bug in the Microsoft C runtime, but we probably need to provide a workaround for it in Python.

Agree that the patches from issue 4804 and wrapping strftime() to catch the invalid_parameter call would fix this:

There does not seem to be any mention of what an ANSI behavior should be upon encountering a non-supported format string. Hence, perhaps, the discrepancy among different platforms.

I don't think this is a Windows "bug" per se, because the behavior is undefined in the standards. The burden is up to us to validate the format string inputted [w]strftime and currently, our code mistakenly clears "%f" as valid.
I'm attaching a patch against 2.7 branch.

Fixed it in relevant branches. I had to add condition around the test to verify that platform was win because this is unique to windows only. Thanks.

Majeed, the fixes for this issue were released several years ago and the issue has been closed. Comments on it will likely be ignored. If you believe there is a problem in the current versions of Python 3 (3.4.3) or Python 2 (2.7.9), please open a new issue with appropriate supporting documentation of how to reproduce the problem (including platforms and versions used) and any resulting tracebacks.
