pretty strange behavior of "strip"

[Guy Doune]

Hi everybody,

Could it be a bug?????

Python 2.5.2 (r252:60911, Jul 31 2008, 17:28:52)
[GCC 4.2.3 (Ubuntu 4.2.3-2ubuntu7)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
 >>> test=['03.html', '06.html', 'questions.html', '04.html', 
'toc.html', '01.html', '05.html', '07.html', '02.html', '08.html']
 >>> test
['03.html', '06.html', 'questions.html', '04.html', 'toc.html', 
'01.html', '05.html', '07.html', '02.html', '08.html']
 >>> test[4]
'toc.html'
 >>> test[4].strip('.html')
'oc'

Can't figure out what is going on, really.
