first_and_last_4

can't figure it out why it isn't happy with this code? 

def first_and_last_4(num):
     f4 = num[:4]
     l4 = num[-4:]
     return f4 + l4

thanks in advance!

Hey Ariel, I'm not an expert at Python, but it seems to be pretty picky about the spacing of your functions. Changing the indentations to line up seemed to make the argument pass the challenge without changing anything else.

Before:

def first_and_last_4(num):
     f4 = num[:4]
     l4 = num[-4:]
     return f4 + l4

After:

def first_and_last_4(num):
    f4 = num[:4]
    l4 = num[-4:]
    return f4 + l4
