How to concatenate element-wise two lists in Python?

Question

I have two lists and I want to concatenate them element-wise. One of the list is subjected to string-formatting before concatenation.

For example :

Answer 1

Using zip

[m+str(n) for m,n in zip(b,a)]

output

['asp10', 'asp11', 'asp15', 'asp16', 'asp210', 'asp211']
