Question

所以我们有一个学校项目来制作一个程序，询问用户是从52平台挑选一张随机卡还是模拟抛硬币 - 头或尾。我有一个测试版工作，但我正在研究如何使该程序更有效。基本上，该程序将元组“卡”和“硬币”设置为所有可能的类型，因此对于硬币，头部和尾部以及卡片，52种不同的卡片。

程序的以下部分将变量“choice”设置为卡片或硬币

    while choice!='card' and choice!='coin':
            choice=input("Pick a card or toss a coin (card/coin)?: ")
            if choice!="card" and choice!="coin":
                print("Please enter either 'card' or 'coin'...")
                time.sleep(2)

接下来我希望能够根据'choice'的值从任一元组返回一个值，而不使用if和if语句，具体如下：

    print("The ",choice," picked at random is... ",random.choice("Either card, or coin"),"!")

我该怎么做？谢谢，布兰登。

#setting variable 'repeat' to 'y' to start the mainloop of the program
repeat="y"
while repeat=="y":

    #blanking the repeat and choice variables so they can be reset later
    repeat=""
    choice=""

    #won't allow the user to continue until either 'card' or 'coin' is entered
    while choice!='card' and choice!='coin':
        choice=input("Pick a card or toss a coin (card/coin)?: ")
        if choice!="card" and choice!="coin":
            print("Please enter either 'card' or 'coin'...")
            time.sleep(2)


    print("The ",choice," picked at random is... ",random.choice(card),"!")


    #won't allow the user to continue until either 'y' or 'n' is entered
    while repeat!="y" and repeat!="n":
        repeat=input("Go again..? (y/n): ")
        if repeat!="y" and repeat!="n":
            print("Please enter either 'y' for yes or 'n' for no...")
            time.sleep(2)

#ending of the program
print("Goodbye!")
time.sleep(2)

Answer 1

实现这一目标的最简单方法是使用元组字典：

items = { 'coin': coin,
          'card': cards }

然后，在choice循环正确设置while之后，使用用户提供的单词作为键从字典中选择正确的列表，然后将其传递给{ {1}}：

random.choice

Answer 2

我确定这是你要问的问题，但如果您正在谈论的元组是('coin', 'card')，那么您可以执行以下操作：

import random

test = ('coin', 'card')
test[random.randint(0, 1)]

这将随机选择两个选项中的一个。
