[New-bugs-announce] [issue22139] python windows 2.7.8 64-bit wrong binary version

[Andreas Richter]

New submission from Andreas Richter:

Having the following problem.
1. Download 2.7.8 64-bit windows msi
2. Install it
3. Run python ... says it's 2.7.6
4. Execute import hmac
5. Error

Output:
C:\prototype>python
Python 2.7.5 (default, May 15 2013, 22:44:16) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import hmac
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\prototype\Tools\python27\lib\hmac.py", line 8, in <module>
    from operator import _compare_digest as compare_digest
ImportError: cannot import name _compare_digest

I saw some posts out there indicating it had something to do with django or something related, but when I run python -v I can see that it's only involving local python libraries (in fact no site-packages at all)
The problem is that the builtin version of the operator module (which incidentally is not loaded from a pyd or pyc file (meaning it's inside of either python27.dll or python.exe doesn't contain _compare_digest.)
Most of the time to get things to run you can just delete the import line if you can make sure not to call hmac.compare_digest.
