Good personal and possible add comma in an example string: 

a = '1234567890abcdefghijklmnopqrstuvwxyz_'

So that she stays like this a = 1,2,3,4,5,6,7....

Do the following: 

lst = list(a) // transforma sua string em lista 
txt = ",".join(lst) // coloca vírgula entre as letras

Note that this can be done in just one step: 

a = ",".join(a)
