python 猜谜游戏练习

Question

我目前正在做 learnpython.org 的 python 练习：我在使用加粗的额外练习时遇到了问题：

生成一个1到9之间的随机数（包括1和9）。让用户猜数字，然后告诉他们猜的是太低、太高还是完全正确。（提示：记得使用第一个练习中的用户输入课程）

额外内容：

继续游戏直到用户输入“退出”

记录用户猜了多少次，当游戏结束时打印出来。

到目前为止，这是我的代码：

import random


def gameTracker():
    global playedGames
    playedGames = 1
    playedGames = playedGames+1

def generateNumber():
    global generatednumber
    generatednumber = random.randint(1, 9)

def generateuserGuess():
    global userguess
    userguess = int(input('Pick a number between 1-9: '))


def generationProcess():
    global userguess
    if int(userguess) == generatednumber:
        print('You have guessed the number. Congratulations.')
        gameTracker()
        global playAgain
        playAgain = input('Want to play again? y/n: ')
        if playAgain == 'y':
            generateNumber()
            userguess = input('Pick a new number between 1-9: ')
            generationProcess()
        if playAgain == 'n':
            print('The game has ended. You have played: ')
            print(int(playedGames))
            print('games')

    if int(userguess) > generatednumber:
        print('You have guessed too high.')
        global conConfirm
        conConfirm = str(input('Guess again?: c/quit: '))
        conGame()

    if int(userguess) < generatednumber:
        print('You have guessed too low.')
        conConfirm = str(input('Guess again?: c/quit: '))
        conGame()


def conGame():
    if conConfirm == 'c':
        global userguess
        userguess = int(input('Your new guess please: '))
        generationProcess()

    if conConfirm == 'quit':
          print('The game has ended. You have played: ')
          print(int(playedGames))
          print('games')

generateNumber()
generateuserGuess()
generationProcess()

当用户在玩完后按'n'或'quit'时，它不会打印出正确的游戏数，这意味着gameTracker()被写成badly/wrong，但是由于某种原因，它还会打印游戏的播放次数 * playAgain == 'n'.

之后会发生什么

我将如何完成这项工作？

Answer 1

在您的 gameTracker() 代码中，您将 playedGames 初始化为 1，然后递增它。所以它看起来总是存储值 2.

由于你的递归，你得到了多个输出。在最后一次递归调用后，程序控制回到 if 语句，变量的值仍然是 'n' 或 'quit' 将再次打印详细信息。您可以在退出条件后将变量初始化为不同的值以避免这种情况。

import random

playedGames = 0

def gameTracker():
    global playedGames
    playedGames = playedGames+1

def generateNumber():
    global generatednumber
    generatednumber = random.randint(1, 9)
    gameTracker()

def generateuserGuess():
    global userguess
    userguess = int(input('Pick a number between 1-9: '))


def generationProcess():
    global userguess
    global generatednumber
    if int(userguess) == generatednumber:
        print('You have guessed the number. Congratulations.')
        global playAgain
        playAgain = input('Want to play again? y/n: ')
        if playAgain == 'y':
            generateNumber()
            userguess = input('Pick a new number between 1-9: ')
            generationProcess()
        if playAgain == 'n':
            print('The game has ended. You have played: ')
            print(int(playedGames))
            print('games')
            playAgain = 'x'


    if int(userguess) > generatednumber:
        print('You have guessed too high.')
        global conConfirm
        conConfirm = input('Guess again?: c/quit: ')
        conGame()

    if int(userguess) < generatednumber:
        print('You have guessed too low.')
        conConfirm = str(input('Guess again?: c/quit: '))
        conGame()


def conGame():
    global conConfirm
    if conConfirm == 'c':
        global userguess
        userguess = int(input('Your new guess please: '))
        generationProcess()

    if conConfirm == 'quit':
          print('The game has ended. You have played: ')
          print(int(playedGames))
          print('games')
          conConfirm = 'x'

generateNumber()
generateuserGuess()
generationProcess()

Answer 2

你应该在 gameTracker() 方法中声明后增加 generateNumber() 方法中玩的游戏数量。这样，无论玩了多少游戏，您都可以跟踪玩了多少游戏！它看起来像这样：

def gameTracker():
    global playedGames
    playedGames = 0

def generateNumber():
    global generatednumber
    generatednumber = random.randint(1, 9)
    playedGames += 1

Answer 3

与您的 globals 和 function returns 一起工作。我已经调整了您代码中的一些错误并添加了一些注释。浏览一下！

import random

#create variable for num of played games
playedGames = 0

#creat variable to count number of guesses per game
guesses = 0
#create function to generate new random num
def generateNumber():
    return random.randint(1, 9)

#askk initial question

generatednumber = generateNumber()

userguess = int(input('Pick a number between 1-9: '))

def generationProcess():
    global userguess, guesses, playedGames,generatednumber

    while True:


        if userguess == generatednumber:
            print('You have guessed the number. Congratulations.')
            playedGames += 1
            global playAgain
            playAgain = input('Want to play again? y/n: ')
            if playAgain == 'y':
                generatednumber = generateNumber()
                userguess = input('Pick a new number between 1-9: ')
                generationProcess()
            if playAgain == 'n':
                print('The game has ended. You have played: '+ str(playedGames)+' games')

        elif int(userguess) > generatednumber:
            print('You have guessed too high.')
            guesses+=1
            conConfirm = str(input('Guess again?: c/quit: '))
            conGame(conConfirm)

        elif int(userguess) < generatednumber:

            guesses+=1
            print('You have guessed too low.')
            conConfirm = str(input('Guess again?: c/quit: '))
            conGame(conConfirm)


def conGame(conConfirm):
    global userguess
    if conConfirm == 'c':
        userguess = int(input('Your new guess please: '))
        generationProcess()

if conConfirm == 'quit':
    print('The game has ended. You have played: ' + str(playedGames) + ' games')


generationProcess()
