Problems with datetime.datetime.strptime

[Tuomas Vesterinen]

I hoped that I could get rid of my special module _strptime2 when 
porting to Python 3.0. But testing is a disappointment.

Python 3.0.1 (r301:69556, Apr 14 2009, 14:30:31)
[GCC 4.1.2 20070925 (Red Hat 4.1.2-27)] on linux2

...     test_cases = [
...         locale.nl_langinfo(locale.D_T_FMT), # test default formats

...         locale.nl_langinfo(locale.T_FMT)

...     for form in test_cases:
...         string = val.strftime(form)
...         print("  strftime(%s)=%s" % (repr(form), repr(string)))
...         print("  strptime(%s,%s)=" % (repr(string), repr(form)), 
end=' ')
...         try:
...             val2 = datetime.datetime.strptime(string, form)
...         except ValueError as e:
...             print('\n   ', str(e))

What to do.
