New submission from Sverre Johansen <sverre.johan...@gmail.com>:
There seems to be a platform difference in the way stftime handles
unknown format codes.
In OSX Python removes the percentage sign from the returned string when the
format code is unknown. In Linux it leaves it.
Look at the following example:
This is Python 3.1.2 in Ubuntu:
Python 3.1.2 (r312:79147, Apr 15 2010, 15:35:48)
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import datetime
>>> datetime.datetime.now().strftime("%q")
'%q'
And this is Python 3.1.2 on Max OSX:
Python 3.1.2 (r312:79147, Sep 9 2010, 11:11:24)
[GCC 4.2.1 (Apple Inc. build 5664)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import datetime
>>> datetime.datetime.now().strftime("%q")
'q'
I've gotten the same result in 2.5, 2.6 and 3.1.
FYI, this broke some code that parsed the same string first with strftime, and
then used string interpolation (The mac version
deleted all percentage signs before '('):
>>> datetime.datetime.now().strftime("%Y - %(foobar)s") % {"foobar": "egg"}
This does not work in OSX.
