>>> colors = "red blue green white black"
>>> list(colors)
['r', 'e', 'd', ' ', 'b', 'l', 'u', 'e', ' ', 'g', 'r', 'e', 'e', 'n', ' ', 
'w', 'h', 'i', 't', 'e', ' ', 'b', 'l', 'a', 'c', 'k']

If you don't want the spaces remove them before

>>> list(colors.replace(" ", ""))
['r', 'e', 'd', 'b', 'l', 'u', 'e', 'g', 'r', 'e', 'e', 'n', 'w', 'h', 'i', 
't', 'e', 'b', 'l', 'a', 'c', 'k']

or while

[c for c in colors if not c.isspace()]
['r', 'e', 'd', 'b', 'l', 'u', 'e', 'g', 'r', 'e', 'e', 'n', 'w', 'h', 'i', 
't', 'e', 'b', 'l', 'a', 'c', 'k']

converting to a list. Note that c.isspace() is true for all whitespace 
chars; use [... if c != " "] if you want to omit " " only.
