Hi Yannis,

You've got the right idea - you just left off the colon after your function declaration! Syntax will get you :blush:. Always look for typos first. They trip up everyone.

def first_4(b):
    return b[0:4]

Note you can also leave off the zero at the beginning of a slice:

def first_4(b):
    return b[:4]

Cheers :beers:

-Greg

Hi Ari,

Thanks for helping out in the Community. When answering questions, it's always best to give an explanation. Giving students the answers without explanations doesn't help them learn!
