Question

我希望在我的骰子游戏结束时有一个选项：

你想重启吗？是或否

如果用户输入yes，游戏将重新启动并且无限次，直到用户已经有足够的游戏并退出。

我知道你可以用循环来做到这一点，但是怎么样？

Answer 1

您可以将游戏包装到函数中，例如game()，并在无限循环中执行它。如果用户说“否”它退出循环，否则它会再次运行。等等...

while True:
    game()
    restart = input('do you want to restart Y/N?)
    if restart == 'N'
        break
    elif restart == 'Y':
        continue

Answer 2

您可以使用while循环来实现此选项。

以下是一个示例实现：

import random

# Instructions for starting the game

while True:
    print("Type 'go' to roll")
    dieroll = input()
    if dieroll == 'go':
        myNumber, pcNumber = random.randint(1,6), random.randint(1,6)
        print("You rolled " + str(myNumber))
        print("He rolled " + str(pcNumber))
        if myNumber <= pcNumber:
            print("You lose!")
        else:
            print("You win!")

    print("Do you want to restart ? Yes or No")
    response = input()
    if not response == "Yes":
        break

Answer 3

首先，您应该将代码打包到函数中，例如

def game():
    your code

对于用户提示，您可以在Python 3.x中使用raw_input（） - Python 2.x和input（）在程序结束时尝试添加如下内容：

answer = raw_input("Restart?")
if answer == "Yes":
    print "Leaving the game"
    sys.exit(0) # import sys module 
elif answer == "No":
    print "Starting new game"
    game()

Answer 4

将程序划分为每个任务的单独函数是个好主意。它易于阅读和修改，因此可以轻松创建和实现重启功能。

函数restart（）根据用户输入返回bool。主startGame循环在while循环的每次迭代中检查此值。

当用户想要停止播放（False）时，该功能返回并且程序停止。

import random

def rollDie():
    myNumber = random.randint(1, 6)
    pcNumber = random.randint(1, 6)

    print("You rolled %d" % myNumber)
    print("The PC rolled %d" % pcNumber)

    if myNumber > pcNumber:
        return "--- You win! ---"
    else:
        return "--- You lose! ---"

def restart():
    user_input = input("Would you like to play again? Type 'Yes' or 'No'\n\n")

    if user_input.lower() == "no": # Converts input to lowercase for comparison
        return False
    elif user_input.lower() == "yes":
        return True

def startGame():
    while True:
        user_input = input("Dice Game: Try to roll a bigger number than the computer! Good Luck \n" +
                          "Type 'go' to roll the die... \n\n")

        if user_input == "go":
             print(rollDie())
            if not restart():
                return

startGame()

我刚刚提交了类似问题的帖子。如果这有帮助，请告诉我：

Simple Python Game Restart Solution

为了满足您的特定需求，您可以将重启代码更新为如下所示，以允许输入是/否输入选项。

play_again = input("Do you want to restart? Yes or No\n")

if play_again == "Yes":
    exec(open("./yourfilenamehere.py").read())
else:
    exit()

如何插入重启游戏选项？
