用python 写一个餐馆菜单管理系统

好的，下面是一个简单的餐馆菜单管理系统的Python代码，包含添加菜品、查看菜单以及删除菜品等功能：

menu = {}

def add_dish(name, price):
    menu[name] = price
    print(f"{name} added to the menu with a price of {price}.")

def view_menu():
    print("MENU:")
    for name, price in menu.items():
        print(f"{name} - {price}")

def delete_dish(name):
    if name in menu:
        del menu[name]
        print(f"{name} has been removed from the menu.")
    else:
        print(f"{name} is not in the menu.")

while True:
    print("1. Add dish")
    print("2. View menu")
    print("3. Delete dish")
    print("4. Exit")
    choice = input("Enter your choice (1-4): ")

    if choice == "1":
        name = input("Enter the name of the dish: ")
        price = input("Enter the price of the dish: ")
        add_dish(name, price)
    elif choice == "2":
        view_menu()
    elif choice == "3":
        name = input("Enter the name of the dish to delete: ")
        delete_dish(name)
    elif choice == "4":
        print("Goodbye!")
        break
    else:
        print("Invalid choice. Please enter a number from 1 to 4.")

以上代码实现了一个简单的餐馆菜单管理系统，用户可以通过输入不同的选项来实现添加菜品、查看菜单和删除菜品等功能。
