Popcorn hack 1

def output(x):
    print(2 * (x + 8) - 1)

output(5)
   

25

Popcorn hack 2

number1 = 3
number2 = 1
number3 = number1 % number2
number4 = number3 * number1 + 50
print(number4)

50

Popcorn Hack 3

numbers = [1, 2, 3, 4, 5]

for num in numbers:
    remainder = num % 2
    if remainder == 0:
        print(num, "is divisible by 2")
    else:
        print("The remainder when", num, "is divided by 2 is", remainder)

The remainder when 1 is divided by 2 is 1
2 is divisible by 2
The remainder when 3 is divided by 2 is 1
4 is divisible by 2
The remainder when 5 is divided by 2 is 1
