Python Split String dont work

Question

No matter what I try, this string is not split.

def funktion():
    ser = serial.Serial('COM5',115200)
    b = str("Das ist ein Test")
    a = str(ser.readline().decode())
    b.split(' ')
    a.split('s')
    print (a)
    print (b)

Please use plain text to show the output of your code instead of a screenshot. — chepner, Jan 29 '17 at 15:41

String aren't mutable, so you have to re-assign those:

b = b.split(' ')
a = a.split('s')
print(a)
print(b)

See more on Immutable vs Mutable types SO question and in that article.

the split function does not change the string in-place. it returns a new string. you must do tokens = b.split(' '); print(b) instead.
