【问题描述】：

想要有一个输入变量来问一个问题，其中包含许多合适的 true 语句，但根据用户输入的内容给出不同的答案。我当前的代码与下面类似，但 niot 工作正常。

我只想打印一个语句或另一个。我还想让这种代码组合适用于许多其他答案，比如“也许你有什么？” “有便宜的吗？” “我想要随机的东西！”

我的代码如下所示：

menu_decision = input('would you like to see the menu?') ####input variable for coustmers decision
if 'yes':
    print('todays menu: ' + combo_1 + combo_2 + combo_3)
elif 'no':
    exit('Have a nice day!')
elif 'what do you have?':
    print('todays menu: ' + combo_1 + combo_2 + combo_3)
elif 'I want something random!"
    randomizer = input('what is your food preference?')

print('combo shack') ##title of my program
combo_1 = 'FOOD1, ' ###variable 1
combo_2 = 'FOOD2, ' ###variable 2
combo_3 = 'FOOD3 ' ####variable 3

menu_decision = input('would you like to see the menu?') ####input variable for coustmers decision
if menu_decision := 'yes': ####if yes print menu with all three  varibles
    print('todays menu: ' + combo_1 + combo_2 + combo_3)
        #cookie_randomizer= input("how many combos would you like?:")

elif menu_decision := 'no': ###if no dismiss coustmer
    exit('Have a nice day!')

Python 使用 == 检查字符串条件匹配，例如

print('combo shack')### title of my program
combo_1 = 'FOOD1, ' ### variable 1
combo_2 = 'FOOD2, ' ### variable 2
combo_3 = 'FOOD3 '  ### variable 3

menu_decision = input('would you like to see the menu?') #### input variable for coustmers decision

if menu_decision == 'yes':
    print('todays menu: ' + combo_1 + combo_2 + combo_3)

elif menu_decision == 'no': 
    exit('Have a nice day!')

elif menu_decision == 'I want something random!':
    randomizer = input('what is your food preference?')
