Hello,
This function does I what I want. But I'm wondering if there is an
easier/better way. To be honest, I don't have a good understanding of
what "pythonic" means yet.
def divide_list(lst, n):
"""Divide a list into a number of lists, each with n items. Extra
items are
ignored, if any."""
cnt = len(lst) / n
rv = [[None for i in range(n)] for i in range(cnt)]
for i in range(cnt):
for j in range(n):
rv[i][j] = lst[i * n + j]
return rv
Thanks!
See the last recipe from:
http://docs.python.org/lib/itertools-recipes.html. It's not doing
quite the same thing, but gives an illustration of one way to approach
this sort of thing.
