It says I'm not getting the right values back

I think it is the way I'm writing the return statement. I've tried many ways and can't get it right.

slices.py 
def first_4(data):
    return data[:4]

def first_and_last_4(data):
    return data[:4], data[-4:]

As an example your code

first_and_last_4("12345678")

returns

('1234', '5678')

whereas you are asked to return a single value. Try concatenation. 

def first_and_last_4(data):
    return data[:4] + data[-4:]
