Let's not forget the much simpler solutions:

    >>> def eight(x): return 8
    ...
    >>> eight("Aug")
    8

and:

    >>> 8
    8


BTW, is this a bug:

   >>> import locale
   >>> locale.getlocale()
   ('de_DE', 'UTF-8')
   >>> import time
   >>> time.strptime("Dez", "%b").tm_mon
   Traceback (most recent call last):
     File "<stdin>", line 1, in <module>
     File "/usr/lib/python3.2/_strptime.py", line 482, in _strptime_time
       tt = _strptime(data_string, format)[0]
     File "/usr/lib/python3.2/_strptime.py", line 337, in _strptime
       (data_string, format))
   ValueError: time data 'Dez' does not match format '%b'
   >>> time.strftime("%b", time.localtime(time.time() + 120 * 86400))
   'Dec'
   >>> time.strftime("%x")
   '08/14/14'

After all, "%b" is documented as "Locale’s abbreviated month name."

Anyway, "%b" *should* depend on the locale, so str[pf]time may not be
suitable to deal with email dates, for example.
