错误：

Traceback (most recent call last):
  File "C:\Users\Boys\Desktop\3 Round Quiz.py", line 24, in <module>
    if difi == ("Easy"):
NameError: name 'difi' is not defined

当我输入＆＃39; 1＆＃39;上面的错误出现了。玩游戏＆＃39;猜数字＆＃39;它提出了这一点，即使变量difi用于测验。我不确定为什么会这样，所以任何帮助都将不胜感激！感谢

Answer 1

difi只有在quiz为1时才会被绑定：

if quiz == 1:
    print("Would you like to play 'Easy' or 'Hard'?")
    difi = input()

除此之外，您不设置difi，并且在这种情况下未定义名称。

quiz从0开始，除非你选择'2'，否则不会递增：

elif game == ("2"):
    quiz = quiz + 1

另一方面，如果您选择“1”，则quiz保持为0，difi未设置，并且您的代码会中断。

Answer 2

控制流在定义if difi == ("Easy"):之前到达difi行，因为quiz在顶部仍为0。我怀疑您希望代码的if difi == ("Easy"):和相关部分缩进更多，以便它们出现在if quiz == 1:块中。

我不明白为什么在我的游戏中抛出NameError
