Learning Objectives

  1. Input N number of items from the user
  2. Add a dictionary into another dictionary (nested)
  3. Loop over items in a dictionary
  4. If statements for items in a dictionary
  5. Print statements for total cost

Hint:: prices are in float and numberinstock is integers.

I am giving the following code:

def get_total_cost(all_products):
    total = 0.0
    ''' Write your code here'''
    return total

 

if __name__ == "__main__":
    n = int(input())
    all_products = {}
    ''' Write your code here'''

Hint: prices are in float and numberinstock is integers. Example: Input 3. banana 2 10 strawberry 3 30 apple 1.5 20 Output { 'banana': {'price': 2.0, 'number_in_stock': 10}, 'strawberry': {'price': 3.0, 'number_in_stock': 30}, 'apple': {'price': 1.5, 'number_in_stock': 20}} The total cost of all the products is $140.0 354684.2266598.qx3zqy7

Instructions You own a shop and you need to calculate the total cost if you sold all your products. In order to do that, you asked a programmer to write you a program that takes all the products you have with their prices and number in stock. The result of the program should be the total price of all the products in your stock. 1. Get a number N from the user for the number of products the user will enter. 2. Loop N times to get the product, price, numberinstock for each product (all in the same line) and save this information in a dictionary with this structure: { 'banana' { price: 10, number_in_stock: 5 } } Add this dictionary in a all_products dictionary. 3. After saving all the user's information, call function get_total_cost to get the total cost of all the products 4. Function get_total_cost should be implemented as follows: 4.1 Loop over the dictionary in the function parameters all_products 4.2 Check if numberinstock is greater than 0, then calculate the price of this product by numberinstock * price for this product 4.3 Add the result of step 4.2 to the total cost 4.4 Return the total cost 5. Print (outside the function) the all_products dictionary 6. Print (outside the function): "The total cost of all the products is $<total_cost>" Hint: prices are in float and numberinstock is integers.
