Merge two strings with alternate chars as output

Question

I got the task to alternately combine the letters of two strings with the same length.

For example:

Inputstring 1: \"acegi\"

Inputstring 2: \"bdfhj\         


        

Answer 1

One can simply use map with join to get desired result:

"".join(map(lambda x,y: x+y, astr, bstr))

zip in not needed here since 2 strings/lists can be provided to map which has a lambda function that takes 2 arguments. Also, + symbol works to concatenate 2 strings here.
