I have to define a function called is_prime that takes a number x as input, then for each number n from 2 to x - 1, test if x is evenly divisible by n. If it is, return False. If none of them are, then return True.

The system I'm using (codecademy) has given my code the error message "Oops, try again. Does your is_prime function take exactly one argument (an integer)? Your code threw a "unsupported operand type(s) for %: 'int' and 'list'" error."

Please could someone to fix my code with an explanation of how my code is wrong?

def is_prime(x):n = range(2, x-1)if x % n == 0:return Falseelse:return True

You need to loop over the range:

 def is_prime(x):if x < 2:return Falsefor i in range(2,x):if x % i == 0:return Falsereturn True

if x % i == 0 never evaluates to True, you have a prime so you return True outside the loop after you have checked each i. You could simply return a gen exp:

def is_prime(x):return x > 1 and not any(x % i == 0 for i in range(2, x))
