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!
x = ['1', '2', '3', '4', '5', '6', '7', '8']
def divide_list(lst, n):
rv = []
for i in range(int(round((len(lst)/n),0))):
rv.append(lst[i*n:(i+1)*n])
return rv
tmp = divide_list(x, 3)
tmp
[['1', '2', '3'], ['4', '5', '6']]
One way to do it.
.
