combine data from two different strings in python

Question

I have two strings:

a ='hellowww'
b ='world'

Expected Output

c = 'hweolrllodwww'

My code:

for x,y in zip(a,b):
    print(x,y)

Its not working in my case.

Note : Length of two strings ,may not be same.

from itertools import zip_longest; c = ''.join(s + t for s, t in zip_longest(a, b, fillvalue='')) or c = ''.join(s for tup in zip_longest(a, b, fillvalue='') for s in tup) — Steven Rumbalski

zip stops when the shortest iterable is traversed. You can use itertool module instead via chain and zip_longest:

from itertools import chain, zip_longest

res = ''.join(chain.from_iterable(zip_longest(a, b, fillvalue='')))

# 'hweolrllodwww'
