Как удалить товар из корзины ⇐ Python

[Anonymous]

Я делаю «торговую палатку» для магазина и пытаюсь реализовать функцию «удаления», чтобы удалять товары из корзины, но понятия не имею, с чего начать.

Код: Выделить всё

import menu
cart = [] #List to store items in the cart

def print_menu(menu):
print("\n=== MENU ===")
for num, drink in menu.items():
print(f"{num}. {drink['name']} - {drink['price']}")

"""Lets user choose options; matcha, hojicha, view cart, or exit"""

while True:

print("What would you like to order?")

exit()

print("Invalid choice. Please try again.")

"""Prompts user to enter a drink they'd like to order.
Provides them with the description of the drink they'd like to order
