Do you simply want to turn single characters into a list, or do you want to tokenize the input, i.e. turn 57+23 into ["57", "+", "23"]? - Håvard

Yes, very simply:

>>> s = "5+6"
>>> list(s)
['5', '+', '6']

Using map inbuilt list creation to work

Code:

map(None,"sart")

Output:

['s', 'a', 'r', 't']

You can also use list comprehension like: 

lst = [x for x in "5+6"]
print(lst)

in python 3 you could make this ...

>>> s = 'bioinform'
>>> s
'bioinform'
>>> w = list(s)
>>> w
['b', 'i', 'o', 'i', 'n', 'f', 'o', 'r', 'm']
>>>

but if you give list any value will give you an error so you should restart your IDLE
