"In the previous exercise, you developed a program to manage customer orders and inventory. Now, let's take it a step further and incorporate comprehension into your code.\n",
"\n",
"Follow the steps below to complete the exercise:\n",
"\n",
"1. Review your code from the previous exercise and identify areas where you can apply comprehension to simplify and streamline your code. \n",
"\n",
" - *Hint: Apply it to initialize inventory, updating the inventory and printing the updated inventory.*\n",
" \n",
" - For example, in initializing the inventory, we could have:\n",
" \n",
" ```python\n",
" def initialize_inventory(products):\n",
" inventory = {product: int(input(f\"Enter the quantity of {product}s available: \")) for product in products}\n",
" return inventory\n",
"\n",
" ```\n",
"<br>\n",
" \n",
" \n",
"2. Modify the function get_customer_orders so it prompts the user to enter the number of customer orders and gathers the product names using a loop and user input. Use comprehension.\n",
"\n",
"3. Add a new function to calculate the total price of the customer order. For each product in customer_orders, prompt the user to enter the price of that product. Use comprehension to calculate the total price. Note: assume that the user can only have 1 unit of each product.\n",
"\n",
"4. Modify the update_inventory function to remove the product from the inventory if its quantity becomes zero after fulfilling the customer orders. Use comprehension to filter out the products with a quantity of zero from the inventory.\n",
"\n",
"5. Print the total price of the customer order.\n",
"\n",
"Your code should produce output similar to the following:\n",
"\n",
"```python\n",
"Enter the quantity of t-shirts available: 5\n",
"Enter the quantity of mugs available: 4\n",
"Enter the quantity of hats available: 3\n",
"Enter the quantity of books available: 2\n",
"Enter the quantity of keychains available: 1\n",
"Enter the number of customer orders: 2\n",
"Enter the name of a product that a customer wants to order: hat\n",
"Enter the name of a product that a customer wants to order: keychain\n",
"\n",
"Order Statistics:\n",
"Total Products Ordered: 2\n",
"Percentage of Unique Products Ordered: 40.0\n",
"\n",
"Updated Inventory:\n",
"t-shirt: 5\n",
"mug: 4\n",
"hat: 2\n",
"book: 2\n",
"Enter the price of keychain: 5\n",
"Enter the price of hat: 10\n",
"Total Price: 15.0\n",
"\n",
"```\n"
