Answer:
I wrote this myself, it should be working. I think this is what the instructions were looking for.
The code below should return
Squared: 1296  
Mod: 0        
Quadrupled: 16
Explanation:
def threeParams(squared, mod, quadruples):
    array = [squared, mod, quadruples]
    array[0] = squared ** 2
    array[1] = mod % 5
    array[2] = quadruples * 4
    return array
valueArr = threeParams(36, 15, 4)
print(f"Squared: {valueArr[0]}\nMod: {valueArr[1]}\nQuadrupled: {valueArr[2]}")
 
        
             
        
        
        
This is for Python
name = 'Joe'
print(f'My name is {name}')
This is called string formatting. Using f before the text. This is another way
name = 'Joe'
print('My name is', Joe)
But I found that string formatting is cleaner and much more useful
