Prime number sequence
A prime number is a natural number that is divisible only by 1 or itself (e.g. 3, 7, 11 etc.). However, 1 is not a prime number.
Your task is, given a list of candidate numbers cands
, to filter only prime numbers in a new list primes
.
But first, you need to create a function is_prime()
that returns True
if the input number \(n\) is prime or False
, otherwise. To do so, it's sufficient to test if a number is not divisible by any integer number from 2 to \(\sqrt{n}\).
Tip: you might need to use the %
operator that calculates a remainder from a division (e.g. 8 % 3
is 2
).
The math
module is already imported.
