The list() function will change over a string into a list of single-character strings.
>>> list('hello')
['h', 'e', 'l', 'l', 'o']
https://docs.python.org/3/library/functions.html#list
Indeed, even without changing them over to lists, strings as of now act like lists severally. For instance, you can get to individual characters (as single-character strings) utilizing brackets:
>>> s = "hello"
>>> s[1]
'e'
>>> s[4]
'o'
You can likewise loop over the characters in the string so that you can loop over the components of a list:
>>> for c in 'hello':
... print c + c,
...
hh ee ll ll oo
