有什么问题？ 我似乎无法弄明白，我已经重新编写了3次菜单。 当您选择披萨时，它会被切断
答案 0 :(得分：2)
您必须将selection强制转换为int。它应该工作：
selection = int(raw_input("Enter your choice (0-12): "))
而不是：
selection = raw_input("Enter your choice (0-12): ")
或更大的灵活性：
try:
selection = int(raw_input("Enter your choice (0-12): "))
except ValueError:
selection = 0
答案 1 :(得分：1)
您需要将选择转换为int
selection = int(raw_input("Enter your choice (0-12): "))
使用while循环和try / except来检查所输入的数据是否对所有输入都是正确的可能是个好主意，如果将选择转换为int并且有人输入字符串，则程序将崩溃
