我在 Python 中不断收到 NameError，说没有定义，尽管我确实定义了它们

Question

所以我基于这个资源创建了这个，链接在这里：https://www.derekshidler.com/how-to-create-a-text-based-adventure-and-quiz-game-in-python/

编辑：这里是所有代码的 GitHub 链接：https://github.com/gabby-lucies/Quarter-1-Project/blob/master/intro.py

我目前卡住了，但是，在我的第一个选项中，无论何时选择下面列出的任何选项，我都会收到 NameError 说我的选项未定义。谁能给我任何建议？谢谢！另外，对不起，如果这是一个愚蠢的问题。

Answer 1

我已经查看了你的 github 代码，所以我正在改变我的答案

在您的每个选项功能之后，您会立即调用它，此处显示

def option_animal():
    print("Seriously, you walked towards a strange animal sound just like that?")
    print("Luckily, it is only a Fwomp. It doesn't kill you, but it does glare at you strangely.")
    print("Fwomps are cute, so you want to pet it.")
    print("You also want to take the Fwomp.")
    print("You're also hungry and horrible so you also kind of want to eat the Fwomp.")
    print("What will you do?")
    print("A. Pet Fwomp B. Take Fwomp C. Eat Fwomp") 
    time.sleep(2.5)
    choice = input(">>> ")
    if choice in answer_A:
        fwomp = 1
        option_petfwomp()
    elif choice in answer_B:
        fwomp = 1
        option_takefwomp()
    elif choice in answer_C:
        option_eatfwomp()
    else:
        print(required)
option_animal()

由于python是一种过程语言，因此文件中仅存在此调用之前的代码，因此，在您调用option_animal的位置，option_petfwomp不存在，但是如果您删除所有这些函数调用并将它们移动到文件的末尾，它应该可以工作。

希望对你有帮助

Answer 2

您的代码没有错，只是不完整。我假设您正在使用它来学习 Python。让我问你一个简单的问题。当你按下运行时，你会得到一些选项。

What will you do?
A. Pet Fwomp B. Take Fwomp C. Eat Fwomp

如果我输入“A”并回车，它会运行option_petfwomp()

但是在你的代码中你没有定义这个函数。

如果你添加：

def option_petfwomp():
    print("option_petfwomp")

def option_takefwomp():
    print("option_takefwomp")

def option_eatfwomp():
    print("option_eatfwomp")

你会明白它是如何工作的。基本上，您正在控制程序的流程。如果你定义了这些函数，你就可以从你的游戏中调用它们。

我的建议：

1. 想想你想让你的代码做什么。
2. 将其绘制为图表或伪代码。
3. 编码。

您似乎复制粘贴了代码，却不知道它做了什么，也不知道您想要它做什么。这一切都很好，但是在希望其他人能够为您理解之前，请花点时间理解您的代码。
