hi all,
suppose I have 2 lists
list1 = ['elem0', 'elem1', 'elem2', 'elem3', 'elem4', 'elem5']
and
list2 = [0, 2, 4] # integer elements
howto (I mean most simple recipe, of course) form list3 that contains
elements from list1 with indexes from list2, i.e.
list3 = ['elem0', 'elem2', 'elem4']?
Thank you in advance, D. 7 825

Ok, I use Python 2.5 but I try my code to remain Python 2.4 and
(preferable) 2.3 compatible.
Are there other solutions?

Why don't you try Paul's suggestion under Python 2.3 and see what
happens?

Did you try Paul's suggestion?
Python 2.3.5 (#1, Oct 13 2005, 09:17:23)
[GCC 3.2.3 20030502 (Red Hat Linux 3.2.3-52)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>list1 = ['elem0', 'elem1', 'elem2', 'elem3', 'elem4', 'elem5'] list2 = [0, 2, 4] list3 =[list1[i] for i in list2] list3
['elem0', 'elem2', 'elem4']
Hmm... I thought this issue is available from Python2.5 only. I have
no other interpreters in my recently installed KUBUNTU 8.04.
Thanks all,
D.

"aptitude install python2.4" helps.

This works under python 2.0+, I think.
Before that, you could have written:
list3 = map(list1.__getitem__, list2)
