Traversing two strings at a time python

Question

I have two strings and I want to print them one character at a time alternatively. Like say

s1 = \"Hi\"
s2 = \"Giy\"

for c,d in s1,s2:
    print c
    print         


        

Answer 1

Use zip():

for c, d in zip(s1, s2):
    print c, d,

Note that this does limit the loop to the shortest of the strings.

If you need all characters, use itertools.izip_longest() instead:

from itertools import izip_longest

for c, d in izip_longest(s1, s2, fillvalue=''):
    print c, d,

Your version looped over the tuple (s1, s2), so it would print s1 first, then s2.
