[issue5979] strptime() gives inconsistent exceptions

[Alexander Belopolsky]

Alexander Belopolsky <belopolsky at users.sourceforge.net> added the comment:

Looks like a bug to me:

>>> datetime.strptime("1", "%d")
datetime.datetime(1900, 1, 1, 0, 0)

>>> datetime.strptime('1', '%m')
datetime.datetime(1900, 1, 1, 0, 0)

both %m and %d accept single digits but they should not.

>>> datetime.strptime('123', '%m%d')
datetime.datetime(1900, 12, 3, 0, 0)

>>> import this
..
In the face of ambiguity, refuse the temptation to guess.
