Python Popcorn and Homework Hacks

#Popcorn Hack 1

sum_list = sum(num_list)
print("sum_list = " + str(sum_list))

sum_list = 104

#Popcorn Hack 2

popcorn_price = int(input())
popcorn_bags = int(input())
popcorn_cost = popcorn_price * popcorn_bags

print("Popcorn cost is $" + str(popcorn_cost))

Popcorn cost is $45

# Popcorn Hack 3

for i in range (1, num + 1):
    total_sum += i

print("total_sum = " + str(total_sum))

total_sum = 595

Arithmetic Mean: 4.666666666666667
Median: 5.0

# Homework Hack 2

def collatz_sequence(a):
    sequence = [a]
    while a != 1:
        if a % 2 == 0:
            a = a // 2

            a = 3 * a + 1 
        sequence.append(a)
    
    print("Collatz sequence:", sequence)

# Example usage:
collatz_sequence(6)

Collatz sequence: [6, 3, 10, 5, 16, 8, 4, 2, 1]
