### Instruction: Denmark wants to order pizza.  For toppings, he has 3 cheese, 4 meat and 5 vegetable options, one of which is peppers. He can have only one selection from each topping category (one cheese, one meat and one vegetable). However, if he chooses to have pepperoni, he cannot have peppers. How many topping combinations does he have total? Let's write a Python program.### Response: # define the number of options for each topping
cheese_options = 3
meat_options = 4
vegetable_options = 5

# calculate the total number of combinations
total_combinations = cheese_options * meat_options * vegetable_options

# calculate the number of combinations where pepperoni and peppers are both chosen
# this is simply the number of cheese options, since the meat and vegetable options are fixed as pepperoni and peppers
invalid_combinations = cheese_options

# subtract the invalid combinations from the total combinations
valid_combinations = total_combinations - invalid_combinations

print(valid_combinations)
