Hey Georg! This is a program I wrote for calculating primary numbers in python!

# Python program to check if the input number is prime or not

num = 407

# take input from the user
# num = int(input("Enter a number: "))

# prime numbers are greater than 1
if num > 1:
   # check for factors
   for i in range(2,num):
       if (num % i) == 0:
           print(num,"is not a prime number")
       print(num,"is a prime number")
# if input number is less than
# or equal to 1, it is not prime
   print(num,"is not a prime number")

Also, you should poke around in more! i see you having not a single repl!
