我在哪里把中断放在我的代码中?

print'Personal information, journal and more to come'

while True:

    x = raw_input()
    if x =="personal information": 
         print' Edward , Height: 5,10 , EYES: brown , STATE: IL TOWN:  , SS:'
    elif x =="journal":
       print'would you like  you open a journal or create a new one? open or create'
if x =='createfile':

           file1 = open(completeName , "w")
           toFile = raw_input("Write what you want into the field")
           file1.write(toFile)
           file1.close()

       print'what file would you like to open' 
       y = raw_input()

       break

每当我尝试运行该程序时,它一直告诉我休息时间不在循环中,但我不知道我还能把它放在哪里。还有什么是记住在循环结束处放置休息的好方法?

直言不讳:您的break 不在循环中。你有一个不在while循环中的if语句。

if x =='createfile':缩进的方式,它在while循环运行后运行。

我猜你想要重新编写代码,以便它们都包含在循环中。我还将if更改为elif,因为这似乎更合适:

print 'Personal information, journal and more to come'

while True:

    x = raw_input()
    if x =="personal information": 
         print' Edward , Height: 5,10 , EYES: brown , STATE: IL TOWN:  , SS:'
    elif x =="journal":
         print'would you like  you open a journal or create a new one? open or create'
    elif x =='createfile':
         name_of_file = raw_input("What is the name of the file: ")
         completeName = "C:\\python\\" + name_of_file + ".txt"
         file1 = open(completeName , "w")
         toFile = raw_input("Write what you want into the field")
         file1.write(toFile)
         file1.close()
    elif x =='openfile':
         print'what file would you like to open' 
         y = raw_input()
         read = open(y , 'r')
         name = read.readline()
         print (name)
         break

您的break语句是循环之外的ifelif语句的一部分。 Python是空白敏感的。您应该将所有ifelif语句缩进到循环内。

答案 2 :(得分:0)

你的缩进是错误的。好像你试图突破while循环,但你的while循环结束于

if x == 'createfile'

语句。

你必须修复if和elif语句的缩进,以便它们在while循环中,然后你的break语句才能工作。
