Sieve of Eratosthenes

The Sieve of Eratosthenes is an algorithm used to determine all the prime numbers below a given number.

###Pseudocode

Use the wikipedia explanation above (under the "Example" header) to write some pseudocode to solve this problem. Here is a pseudocode refresher. Write this in comments at the top of the sieve.py file.

###Solve in Python

Write a function that implements this algorithm to determine all the prime numbers below a given number. The program should take a number as an argument, and return an array of all the primes.
