Most pythonic way to interleave two strings

Question

What\'s the most pythonic way to mesh two strings together?

For example:

Input:

u = \'ABCDEFGHIJKLMNOPQRSTUVWXYZ\'
l = \'abcdefghijklmnopqrst         


        

Answer 1

I would use zip() to get a readable and easy way:

result = ''
for cha, chb in zip(u, l):
    result += '%s%s' % (cha, chb)

print result
