Question

我目前正在使用learnpython.org进行python练习：我在加粗的额外例外方面遇到了麻烦：

生成1到9之间的随机数（包括1和9）。让用户猜出数字，然后告诉他们他们是否猜到太低，太高或完全正确。（提示：记得使用第一次练习中的用户输入课程）

附加功能：

让游戏继续进行，直到用户输入“退出”

跟踪用户拍摄的猜测次数，以及游戏何时结束，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()

当用户按下＆＃39; n＆＃39;或者＆＃39;退出＆＃39;在播放之后它并没有打印出正确数量的游戏，这意味着gameTracker()被写错了，但也出于某种原因打印了游戏玩过的次数*之后会发生什么playAgain ==＆＃39; n＆＃39;。

我将如何开展这项工作？

Answer 1

在gameTracker()代码中，将playedGames初始化为1，然后将其递增。所以它看起来总是存储值2.

由于递归，您会得到多个输出。在最后一次递归调用之后，程序控制返回到if语句，变量的值仍为'n'或'quit'将再次打印详细信息。您可以在退出条件之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

在generateNumber()方法中声明后，您应该在gameTracker()方法中增加游戏次数。通过这种方式，您可以跟踪已播放的游戏数量，无论玩多少游戏！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globals和function returns合作。我调整了代码中的一些错误并添加了一些注释。看看！

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()
