需要代码让用户重复尝试

Question

我是编码新手，所以我正在尝试创建剪刀石头布游戏。我几乎完成了游戏，但是当用户和计算机输入相同的数字时，我希望程序重复，直到其中一个玩家获胜。我怎样才能做到这一点？任何帮助表示赞赏。这是我的代码。game = input("Want to play Rock Paper Scissors? (Y/N) ")if game == "Y":  print("1 = Rock, 2 = Paper, 3 = Scissors")  print('')  user = int(input("You have one chance of beating me. Input a number. "))  print('')  import random  computer = random.randint(1,3)  if user == 1 and computer == 1:    print("Must play again! We both played Rock!")  elif user == 1 and computer == 2:    print("You lose! You played Rock and I played Paper!")  elif user == 1 and computer == 3:    print("You win! You played Rock and I played Scissors!")  elif user == 2 and computer == 1:    print("You win! You played Paper and I played Rock!")  elif user == 2 and computer == 2:    print("Must play again! We both played Paper!")  elif user == 2 and computer == 3:    print("You lose! You played Paper and I played Scissors!")  elif user == 3 and computer == 1:    print("You lose! You played Scissors and I played Rock!")  elif user == 3 and computer == 2:    print("You win! You played Scissors and I played Paper!")  elif user == 3 and computer == 3:    print("Must play again! We both played Scissors!")  else:    print("Not a number.")  else:  print("Fine. Bye.")

使用“while 循环”创建“游戏循环”。我从用 python 制作小游戏中学到了这个技巧。此外，您想学习使用“类”作为逻辑，并且可以使用“OOP 概念”改进代码。T 代码已经过测试并且可以工作。

import random

#Create a "function" that meets the requirements of a "game loop"

def gameloop():

    game = input("Want to play Rock Paper Scissors? (Y/N) ")

    

    if game == "Y":

         #Create a "while loop" to host the logic of the game. 

         #Each If statement will enable one "rule" of the game logic.

         #game logic could be redesigned as an "Event".

         #You can add a game "Event System" to your future project backlog

        winner = False

        while not winner:

            print("1 = Rock, 2 = Paper, 3 = Scissors")

            print('')

            user = int(

                input("You have one chance of beating me. Input a number. "))

            print('')

            computer = random.randint(1, 3)

            if user == 1 and computer == 2:

                print("You lose! You played Rock and I played Paper!")

                winner = True

            elif user == 1 and computer == 3:

                print("You win! You played Rock and I played Scissors!")

                winner = True

            elif user == 2 and computer == 1:

                print("You win! You played Paper and I played Rock!")

                winner = True

            elif user == 2 and computer == 3:

                print("You lose! You played Paper and I played Scissors!")

                winner = True

            elif user == 3 and computer == 1:

                print("You lose! You played Scissors and I played Rock!")

                winner = True

            elif user == 3 and computer == 2:

                print("You win! You played Scissors and I played Paper!")

                winner = True

            elif user == 1 and computer == 1:

                print("Must play again! We both played Rock!")

            elif user == 2 and computer == 2:

                print("Must play again! We both played Paper!")

            elif user == 3 and computer == 3:

                print("Must play again! We both played Scissors!")

            else:

                print("Not a number.")

else:

    print("game....over?")

    

gameloop()

我也花时间做了一个 OOP 类示例！它可以通过多种方式进行优化。但是，我希望它能向您展示下一个学习水平！我也希望它能帮助您了解所有您可以在学习时应用的疯狂设计模式和游戏编程技术。

import random

# we can create a player class to be used as an "interface" as we design the games logic

# this will let us scale the features be build in our game

# in this case i will leave it to you to add Wins to the scoreboard to help you learn

class player:

    # your games requerment wants your players to make a choice from 1-3

    choice = 0

    # your games may requerment a player to be defined as the winner

    win = 0

    # your games may requerment a player to be defined as the losser

    loss = 0

class game:

    # by using classes and OOP we can scale the data and logic of your game

    # here we create instances of the class player and define new objects based on your "requerments"

    # your "requerments" where to have one Computer as a player, and one user as a player

    computer = player()

    user = player()

    # this "function" will create a Scoreboard feature that can be called in the 'game loop' or in a future "event" of the game.

    # Like a "Game Stats stage" at the end of the game

    def Scoreboard(self, computer, user):

        Computer = computer.loss

        User = user.loss

        print("+============= FINAL RESULTS: SCOREBOARD!! ======+ ")

        print(" ")

        print("Computer losses: ", Computer)

        print("Player losses: ", User)

        print(" ")

    # Create a "function" that meets the requirements of a "game loop"

           # game logic could be redesigned as an "Event".

           # You can add a game "Event System" to your future project backlog

            winner = False

            while not winner:

                print("1 = Rock, 2 = Paper, 3 = Scissors")

                print('')

                # we create 'Player1' as the user

                Player1 = user

                

                # we change the 'Player1' 'choice' to the user input

                Player1.choice = int(

                    input("You have one chance of beating me. Input a number. "))

                print('')

                

                # we pull in to the game the computer player and call them 'Player1'

                Player2 = computer

                

                # we change the 'Player2' 'choice' to a random number

                Player2.choice = random.randint(1, 3)

            

                if user.choice == 1 and computer.choice == 2:

                    print("You lose! You played Rock and I played Paper!")

                    winner = True

                    user.loss += 1

                elif user.choice == 1 and computer.choice == 3:

                    print("You win! You played Rock and I played Scissors!")

                    winner = True

                    computer.loss += 1

                elif user.choice == 2 and computer.choice == 1:

                    print("You win! You played Paper and I played Rock!")

                    winner = True

                    computer.loss += 1

                elif user.choice == 2 and computer.choice == 3:

                    print("You lose! You played Paper and I played Scissors!")

                    winner = True

                    user.loss += 1

                elif user.choice == 3 and computer.choice == 1:

                    print("You lose! You played Scissors and I played Rock!")

                    winner = True

                    user.loss += 1

                elif user.choice == 3 and computer.choice == 2:

                    print("You win! You played Scissors and I played Paper!")

                    winner = True

                    computer.loss += 1

                elif user.choice == 1 and computer.choice == 1:

                    print("Must play again! We both played Rock!")

                elif user.choice == 2 and computer.choice == 2:

                    print("Must play again! We both played Paper!")

                elif user.choice == 3 and computer.choice == 3:

                else:

                    print("Not a number.")

            # by returning "self" you call the same 'instances' of game that you will define below

            return self.Scoreboard(user, computer)

        else:

            print("game....over?")

# define Instance of game as "test_game"

test_game = game()

# run game loop

test_game.main_loop()

Answer 2

一种方法是使用 while 循环，在满足条件时中断。

while True:

    if (condition):

        print("")

        break

    ...

while 语句重复循环，直到满足其中一个条件。break 语句使程序退出循环并继续执行下一个可执行语句。

Answer 3

您可以将整个 if-elif-block 放在一个 while 循环中，该循环将重复直到您有一个赢家。为了确定是否有赢家，使用布尔变量。

winner = False

while not winner:

    if ...... ## Your if-elif-block

    elif user == 1 and computer == 2:

        print("You lose! You played Rock and I played Paper!")

        winner = True

    ## Your remaining if-elif-block

您只需将命令放在winner=True具有获胜者条件的命令块中。因此，循环将继续，直到您达到这些条件之一。

您还可以选择使用更高级的获胜者变量（0 表示平局，1 表示玩家，2 表示计算机）来使用再见消息中的值。
