How to split a word into letters in Python

Question

I was wondering if there is a straightforward way to do the following:

Input string:

input = 'Hello'

Output string:

output = 'H,e,l,l,o'

I understand you can do list(input), but that returns a list and I wanted to get the string rather than the list.

Any suggestions?

Answer 1

In [1]: ','.join('Hello')
Out[1]: 'H,e,l,l,o'

This makes use of the fact that strings are iterable and yield the individual characters when iterated over.

Answer 2

outputstr = ','.join(inputstr)
