好的，我在第 20 行不断收到缩进错误。我想不通。我的语法看起来不错。我回去删除了所有缩进并重新缩进（以确保混合中没有空格）。为什么给我这个？我该如何解决？

最让我困惑的是我写了相同的代码，但没有导入 EasyGUI 模块，也没有修改 EasyGUI，但除此之外它是相同的代码。if/elif/else 在同一个位置，除了 'eg.msgbox' 省略了 'print' 命令和 raw_input's 被替换为 'boolbox' 之外，一切都相同。

编辑 - 第 20 行是：

 if yon == 0:

if yon == 0:
    choice = eg.boolbox("Was my guess..." , 'High or Low?' , ('High' , 'Low')

您错过了一个右括号。

choice = eg.boolbox("Was my guess..." , 'High or Low?' , ('High' , 'Low'))

另外，检查你的最后一个else:. 它应该是： -

else:
    eg.msgbox("Enter valid input!","Lets start again from the last step")
    continue

你没有if正确缩进你的最后一个： -

    if yon == 0:
        choice = eg.boolbox("Was my guess..." , 'High or Low?' , ('High' , 'Low')
    if choice == 0:
        minimum = middle
        middle = int(round(float(maximum+minimum)/2))
    elif choice == 1:
        maximum = middle
        middle = int(round(float(maximum+minimum)/2))
    else:
        eg.msgbox"Enter valid input!";"Lets start again from the last step"
        continue

你的一切if-elif-else都应该在你的外部如果。您正在检查其中定义的变量的条件..因此将您的结构重新缩进：-

if yon == 0:
    choice = eg.boolbox("Was my guess..." , 'High or Low?' , ('High' , 'Low')
    if choice == 0:
        minimum = middle
        middle = int(round(float(maximum+minimum)/2))
    elif choice == 1:
        maximum = middle
        middle = int(round(float(maximum+minimum)/2))
    else:
        eg.msgbox"Enter valid input!";"Lets start again from the last step"
        continue
