[docs] error in section 5.1.3

[Charles Cihacek]

I just wanted to point out that the first example of 5.1.3 doesn't correctly
list out prime numbers because both 2 and 3 are primes.  The wording should
probably be changed to numbers not divisible by 2 or 3.

Other than that great work, I'm excited to learn python!
