num_items = int(input("How many different items are being purchased? "))

def calculate_subtotal(part_number, description, price, quantity): subtotal = price * quantity print(f"Item: {description}, Part Number {part_number}, subtotal: ${subtotal:.2f} ") return subtotal

def user_input(item_quantity): subtotal = 0.0 for i in range(item_quantity): description = input(' 'f"Enter description of item {i+1} " ) part_number = input(f"Enter part number of item {i+1} ") price = float(input(f"Enter the price of item {i+1} ")) quantity = int(input(f"Enter the quantity for item {i+1} "))

subtotal += calculate_subtotal(part_number, description,price, quantity) return subtotal

if __name__ == '__main__': total = 0.0 total = user_input(num_items)

print(' 'f"Your total is ${total:.2f}")

I need each line of pseudocode in python for this function as much detail that you can provide. "How was each line of this this function made "???

Thanks
