Question

#!/usr/bin/env python
import easygui as eg


start = eg.msgbox('In your head, pick a number between 1 and 100. No matter what, I will guess it in no more than 7 tries. When you think of a number, press OK to start the program.')

maximum = 100
minimum = 0
middle = (maximum-minimum)/2
attempt= 1
while True:
    if attempt > 7:
        eg.msgbox('You cheated. Terminating...')
        break
    else:   
        yon = eg.boolbox("Is your number: " + str(middle) + '?', 'Guess Result',('Yes','No'))
        if yon == 1:
            eg.msgbox("Found in " + str(attempt) + " try!")
            break
        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
        attempt+= 1

好的，我一直在第20行得到缩进错误。我无法弄明白。我的语法很好。我回去删除了所有的缩进并重新缩进它们（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模块而没有EasyGUI修改，但除此之外它是相同的代码。 if / elif / else是在同一个地方，除了'eg.msgbox'省略'print'命令并且raw_input被'boolbox'替换之外，一切都是相同的。

编辑 - 第20行是：

 if yon == 0:

Answer 1

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

你错过了一个结束括号。

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

另外，请检查您的上一个else:。它应该是： -

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

您没有正确缩进上一个if： -

    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

你的所有if-elif-else都应该在你的外面。您正在检查内部定义的变量的条件。因此，将结构重新缩进为： -

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

EasyGUI缩进错误，我不知道为什么
