Yet, if you feed the zip into a list comprehension you get what you
want:
li3 = [''.join(l) for l in zip(li1,li2)]

It's not difficult to write your own

from itertools import *
li3 = list(chain.from_iterable(izip(li1,li2)))

I found zip()
This is the easiest and most pythonic way (IMHO):
l3 = [i+e for i in li1 for e in li2]
l3
['a1', 'a2', 'b1', 'b2']

Hi Python users,
I have two lists:
li1 = ['a', 'b']
li2 = ['1', '2']
and I wish to obtain a list like this
li3 = ['a1', 'a2', 'b1', 'b2']
Is there a handy and efficient function to do this, especially when li1 and li2
are long lists.
I found zip() but it only gives [('a', '1'), ('b', '2')],
