The sieve of Eratosthenes is a way of computing all the prime numbers below a certain number.

Question

The sieve of Eratosthenes is a way of computing all the prime numbers below a certain number. (A prime number is a number that is only divisible by itself and 1)

Implementing this algorithm should be done without any libraries or importing anything to the program.

Implement a function crossoutmultiples() that takes as arguments a list of boolean values (true/false) called is_prime and a number n. The function sets the boolean values at all multiples of n (2*n, 3*n, 4*n ...) that are in the list to false.
Implement a function sieve(n) which gives back a list of all primes below n.
the code :

def crossoutmultiples(isprime,n) :

pass

def sieve(n):

pass
