How do i implement the algorithm below : Get a list of numbers L1, L2, L3....LN as argument
Assume L1 is the largest, Largest = L1
Take next number Li from the list and do the following
If Largest is less than Li
Largest = Li
If Li is last number from the list then
return Largest and come out
Else repeat same process starting from step 3

Create a function prime_number that does the following
Takes as parameter an integer and
Returns boolean value true if the value is prime or
Returns boolean value false if the value is not prime


So far my code is :

def get_algorithm_result(num_list):

    largest =num_list[0]
    
    for item in range(0,len(num_list)):

        if largest < num_list[item]:
            
            largest = num_list[item]

    return largest

    
def prime_number(integer):

    if integer%2==0:
        return False
    else:
        return True
        



After executing the code i get 
"Test Spec Failed

Your solution failed to pass all the tests" 

where I'm i going wrong because i believe my code is correct
