    A certain improvement on @taymon`s answer:

    today = datetime.date.today()
    friday = today + datetime.timedelta( (4-today.weekday()) % 7 )
    

    4 is Friday's weekday (0 based, counting from Monday).
    ( (4-today.weekday()) % 7) is the number of days till next friday (% is always non-negative).

    After seeing @ubuntu's answer, I should add two things:
    1. I'm not sure if Friday=4 is universally true. Some people start their week on Sunday.
    2. On Friday, this code returns the same day. To get the next, use (3-today.weekday())%7+1. Just the old x%n to ((x-1)%n)+1 conversion.
