Question

我正在制作一个冒险游戏，最后我希望它能打印出来，以便用户回答他们是否喜欢游戏，如果愿意，我希望它在.txt文件中写下答案。到目前为止，我希望它打开一个.txt文件并完全写入任何内容，但是不会。它可以单独工作，但是当它放入我的程序时将无法执行。

我尝试移动其位置，尝试尝试if语句和while循环以及效果如何。

import sys


def main():
    play_again = True
    first_choice = True
    fleft_choice = False
    fright_choice = False
    print_thing = True
    while play_again:
        print('Welome to my adventure game, would you like to play?')

        answer = input()
        answer = answer.lower()
        if answer == 'yes' or answer == 'y':
            print('Fantastic, off we go')
        elif answer == 'no' or answer == 'n':
            print('Its your choice')
            break
        else:
            print('invalid input')
            continue

        while first_choice:
            print('You come up to a fork in the road. To the left, you hear a battle raging. To the right is winding '
                  'path that leads to a cave.')

            answer1 = input('which do you choose')
            if answer1 == "left":
                print('you join the fight')
                play_again = False
                first_choice = False
                fleft_choice = True

            elif answer1 == 'right':
                print('you light a tourch and enter the cave')
                play_again = False
                first_choice = False
                fright_choice = True
            else:
                print('invalid input')
                continue

            while fleft_choice:
                print('something happens in battle')
                fleft_choice = False

            while fright_choice:
                print('something is in the cave')
                fright_choice = False

    print('Did you enjoy your adventure?')
    yesfile = open("testfile.txt", "w")
    yesfile.write('lorem ipsum')
    yesfile.close()

    print('would you like to play again?')
    end_answer = input()
    if end_answer == "yes" or end_answer == "y":
        main()
    if end_answer == 'no' or end_answer == 'n':
        sys.exit()


main()

我要弄清楚的是为什么write函数可以单独工作，但是在实现后似乎只是被跳过了。

Answer 1

您确定您的代码不在函数中间的所有while循环中都处于无限循环中吗？这是我想到的最明显的原因。

此外，在使用文件时，建议使用以下类型的语法：

content = "test"
with open("file.txt", 'w', encoding="UTF8") as fp:
    fp.write(content)

这样，您将永远不会忘记保存文件，但是您的文件也应该可以正常工作。

Answer 2

您可以尝试将文件打开，写入和关闭操作括在try-catch块内。返回的错误可以确定问题所在：

try:
    yesfile = open(testfile.txt, "w")
    yesfile.write(output)
    yesfile.close()

except IOError as (number, description):
    print("Error({0}): {1}".format(number, description))

写入我的代码后，write命令不会起作用
