How to split a string into a list of characters in Python?

I've tried to look around the web for answers to splitting a string into a list of characters but I can't seem to find a simple method.

str.split(//) does not seem to work like Ruby does. Is there a simple way of doing this without looping?

Solution 1:

>>> s = "foobar"
>>> list(s)
['f', 'o', 'o', 'b', 'a', 'r']

You need list

You take the string and pass it to list()

s = "mystring"
l = list(s)
print l

You can also do it in this very simple way without list():

>>> [c for c in "foobar"]
['f', 'o', 'o', 'b', 'a', 'r']

If you want to process your String one character at a time. you have various options.

uhello = u'Hello\u0020World'

Using List comprehension:

print([x for x in uhello])

Output:

['H', 'e', 'l', 'l', 'o', ' ', 'W', 'o', 'r', 'l', 'd']

Using map:

print(list(map(lambda c2: c2, uhello)))

Output:

['H', 'e', 'l', 'l', 'o', ' ', 'W', 'o', 'r', 'l', 'd']

Calling Built in list function:

print(list(uhello))

Output:

['H', 'e', 'l', 'l', 'o', ' ', 'W', 'o', 'r', 'l', 'd']

Using for loop:

for c in uhello:
    print(c)

Output:

H
e
l
l
o

W
o
r
l
d
