how convert list of int to list of tuples

Question

I want to convert a list like this

l1 = [1,2,3,4,5,6,7,8]

to

l2 = [(1,2),(3,4),(5,6),(7,8)]

because want to loop

for x,y in l2:
    draw_thing(x,y)

Answer 1

One good way is:

from itertools import izip
it = iter([1, 2, 3, 4])
for x, y in izip(it, it):
    print x, y

Output:

1 2
3 4
