Hello all,
I have a list which contains a bunch of tuples:
mylist = [ ('1', 'Foobar'), ('32', 'Baz'), ('4', 'Snorklings') ]
(The list can potentially be shorter, or much longer). Now I want to
take the first element in each tuple and store it in a list (to use in a
Set later on).
Which would You prefer of the following:
newlist = [ ]
for e in mylist:
newlist.append(int(e[0]))
..or..
newlist = [ None ] * len(mylist)
for i in range(len(mylist)):
newlist.append(int(e[0]))
To me, the second one is more appealing, when I think in terms of
risk of memory fragmentation, etc. But since Python is such a high level
language, I'm not sure my traditional reasoning applies.
