python - 如何重复一段代码

Question

我是Python的初学者，如果用户输入除“否”或"is"以外的任何内容，我想重复答案=raw_input(“你想变得更好吗？”)中的代码，因为在说“你只能选择是或否“代码结束并且不再询问

choosing_options = ["Yes","No"] 


 Answer = raw_input("Do you want to become Better?")    
 if Answer == 'Yes' :
   print 'Great We Will Start Tommorow, meet me at Jhon\'s backyard at 3 AM  '
 elif Answer == 'No' :
     print "Well too bad, meet me again if you change your mind " 
 elif Answer != choosing_options :
      print "You can only choose yes or no!!"  

Answer 1

你只需要一个 while 循环:)

choosing_options = ["Yes","No"] 
answer = None

while (answer not in choosing_options):
    answer = raw_input("Do you want to become better?")

    if answer == 'Yes' :
        print 'Great We Will Start Tommorow, meet me at Jhon\'s backyard at 3 AM  '
    elif answer == 'No' :
        print "Well too bad, meet me again if you change your mind "
