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

you need to use itertools.izip_longest():

In [7]: from itertools import izip_longest

In [8]: s1="Hi"

In [9]: s2="Giy"

In [10]: "".join("".join(x) for x in izip_longest(s1,s2,fillvalue=""))
Out[10]: 'HGiiy'

or using a simple for loop:

s1="Hi"
s2="Giy"
ans=""
for i in range(min(len(s1),len(s2))):
    ans+=s1[i]+s2[i]
ans += s1[i+1:]+s2[i+1:]    
print ans                 #prints HGiiy
