Python石頭剪刀布計分器

Question

我正在做剪刀石頭布游戲。 除了贏/輸/領帶計數器外，一切似乎都運行良好。 我已經看過人們在這里發布的其他一些游戲，但我仍然無法正常工作。 我覺得我太接近了，但我就是做不到。 感謝您的幫助。 這是我第一次在這里發帖，如果我弄亂了格式，我深表歉意。

我編輯了代碼，但仍然無法讓程序在不使用全局變量的情況下識別計數器。 在我編輯的某個時刻，我設法讓它把所有東西都算作平局……我不知道怎么做，我在編輯的某個地方丟失了它。 哈哈。 ——再次感謝大家！

這是我運行程序時得到的：

Please input the correct number according
to the object you want to choose.
Select rock(1), paper(2), or scissors(3): 1
Computer chose PAPER .
You chose ROCK .
You lose!
Play again? Enter 'y' for yes or 'n' for no. y

Answer 1

您的winner_result函數在增加獲勝計數器之前返回。 如果從中刪除所有return語句，則應更新計數器。 無論如何都不需要return語句，因為if/elif/else結構確保只會執行一個可能的結果。

正如 Junuxx 在評論中所說，您還需要正確地將值分配給winner_result變量，即winner_result = 'win'而不是winner_result == 'win' 。 我還會重命名winner_result變量或函數，因為使用相同的名稱會造成混淆。

而win/lose/tie變量目前是本地的，這意味着main和winner_result將擁有這些變量的自己的副本，因此main的值將始終為零。 您可以做的是使它們成為全局變量：在全局范圍內（在任何函數之外）將它們分配為零，並在函數winner_result中添加行global win, lose, tie 。

Answer 2

顯然這個問題已經回答了幾年，但是當我查看相同的信息時它出現了。 如果有人感興趣，這是我的代碼。

#! usr/bin/python3
import random


def game():

    computer_count = 0
    user_count = 0

    while True:
        base_choice = ['scissors', 'paper', 'rock']
        computer_choice = random.choice(base_choice)

        user_choice = input('(scissors, paper, rock) Type your choice: ').strip().lower()
        print()
        computer_wins = 'The computer wins!'
        you_win = 'You win!'

        print(f'You played {user_choice}, the computer played {computer_choice}')
        if user_choice == 'scissors' and computer_choice == 'rock' or \
           user_choice == 'paper' and computer_choice == 'scissors' or \
           user_choice == 'rock' and computer_choice == 'paper':
            print(computer_wins)
            computer_count += 1

        elif user_choice == 'rock' and computer_choice == 'scissors' or \
            user_choice == 'scissors' and computer_choice == 'paper' or \
                user_choice == 'paper' and computer_choice == 'rock':
                print(you_win)
                user_count += 1

        else:
            if user_choice == computer_choice:
                print('Its a draw!')
                computer_count += 1
                user_count += 1

        print(f'Computer: {computer_count} - You: {user_count}')
        print()


game()

我試圖做同樣的項目，我找到了一個適合我的解決方案。

from random import randint

win_count = 0
lose_count = 0
tie_count = 0

# create a list of play options
t = ["Rock", "Paper", "Scissors"]

# assign a random play to the computer
computer = t[randint(0, 2)]

# set player to false
player = False

print()
print("To stop playing type stop at any time.")
print()
while player == False:
    # set player to True
    player = input("Rock, Paper or Scissors? ")
    if player.lower() == "stop":
        print()
        print(
            f"Thanks for playing! Your final record was {win_count}-{lose_count}-{tie_count}")
        print()
        break
    if player.title() == computer:
        print()
        print("Tie!")
        tie_count += 1
        print()
    elif player.title() == "Rock":
        if computer == "Paper":
            print()
            print(f"You lose. {computer} covers {player.title()}.")
            lose_count += 1
            print()
        else:
            print()
            print(f"You win! {player.title()} smashes {computer}.")
            win_count += 1
            print()
    elif player.title() == "Paper":
        if computer == "Scissors":
            print()
            print(f"You lose. {computer} cuts {player.title()}.")
            lose_count += 1
            print()
        else:
            print()
            print(f"You win!, {player.title()} covers {computer}.")
            win_count += 1
            print()
    elif player.title() == ("Scissors"):
        if computer == "Rock":
            print()
            print(f"You lose. {computer} smashes {player.title()}.")
            lose_count += 1
            print()
        else:
            print()
            print(f"You win! {player.title()} cuts {computer}.")
            win_count += 1
            print()
    else:
        print()
        print("Sorry, we couldn't understand that.")
        print()
# player was set to True, but we want it to be false to continue loop
print(f"Your record is {win_count}-{lose_count}-{tie_count}")
print()
player = False
computer = t[randint(0, 2)]

Answer 4

這有效（有點）頁面頂部的代碼有很多問題。 首先，評分不起作用。 其次，沒有縮進意味着其他 def 函數內部的任何內容都不起作用。 第三，在第一個 def main 語句中引用了其他 def 函數，這導致 Python 顯示無效語法，因為 Python 不知道其他函數在它們被引入 python 之前被引用。
