Final answer:
To create a Python Shopping Cart Program that calculates the gross cost, net cost, and includes a tax rate, follow these steps: define the main function, create separate functions for calculating gross and net costs, call those functions in the main function, and print the results.
Step-by-step explanation:
In order to create a Python Shopping Cart Program that calculates the gross cost, net cost, and includes a tax rate, you can follow these steps:
- Define the main function and use input statements to get the necessary input from the user, such as the cost of items.
- Create a separate function called calculate_gross_cost that takes the cost of items as a parameter and multiplies it by 1 plus the tax rate to get the gross cost.
- Create another separate function called calculate_net_cost that takes the gross cost as a parameter and subtracts the tax from it to get the net cost.
- In the main function, call the calculate_gross_cost function to get the gross cost and store it in a variable.
- Next, call the calculate_net_cost function, passing the gross cost as a parameter, to get the net cost and store it in another variable.
- Finally, print out the gross cost and net cost.
Here's an example code implementation:
tax_rate = 0.0875
def calculate_gross_cost(cost):
return cost * (1 + tax_rate)
def calculate_net_cost(gross_cost):
return gross_cost - (gross_cost * tax_rate)
def main():
cost = float(input("Enter the cost of items: "))
gross_cost = calculate_gross_cost(cost)
net_cost = calculate_net_cost(gross_cost)
print("Gross cost: $", round(gross_cost, 2))
print("Net cost: $", round(net_cost, 2))
main()
