Python newbie: I've got this simple task working (in about ten
different ways), but I'm looking for the "favoured" and "most Python
like" way.
Forwards I can do this
for t in listOfThings:
print t
Now how do I do it in reverse? In particular, how might I do it if I
only wanted to iterate part-way through (with a conditional test and a
break), or if I had a large list ?
reverse( listOfThings )
for t in listOfThings:
print t
As reverse() operates in-place I often can't do this. I'm also
(slightly) concerned about possible inefficiency issues of manipulating
a big list just to scan a peek at its tail.
Currently I'm doing this:
for i in range( len( listOfThings )-1, 0, -1):
t = listOfThings [i]
print t
Is this the optimum ? Would xrange() be a better choice (and when is
it a "big" list) ?
Thanks for any guidance
