Prime numbers

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41,
43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97 ...

Prime number

a number that is divisible only by itself and 1 (e.g. 2, 3, 5, 7, 11)
suppose a number 'n' it can be divided by if '1' and only by itself then it can be a prime number

Prime number

def is_prime(n):
  if(n<0):
    print("n is not a nature number!")
    return False
  for i in range(1,ceil(n/2)+1):
    if (i != n and i != 1 and n%i == 0):
      return False
  return True
print(is_prime(int(input("number>>"))))
