#setBirthday sets their Birthday to a date 
    def setBirthday(self): 
     while True: 
      try: 
       day = int(raw_input('Please enter the date of the month (1-31) you were born on here ->')) 
       if day <= 0 or day >= 32: 
        print "better try again..." 
      except ValueError: 

       continue 
      else: 
       break 

       month = int(raw_input('Please enter the month of the year (1-12) you were born on here ->')) 
       if month <= 0 or day >= 13: 
        print "better try again..." 
      except ValueError: 

       continue 
      else: 
       break 
       year = int(raw_input('Please enter the year you were born (19xx or 20xx) here ->')) 

       self.birthday = datetime(year, month, day) 
       print str(varPerson.getName()) + " you were born on " + str(month) + "/" + str(day) + "/" + str(year)

縮進錯誤就在varPerson的最後3行之上。我嘗試過並嘗試使這種情況與異常一起工作，以便能夠有一個流暢的運行腳本，以便在值不合適時允許進行額外的嘗試。建議？我一直在使用這個鏈接幫助：對應的except塊Try and catch method，python，indentation error can not put it out

爲什麼你在循環中放置了一堆方法定義？還有一個'嘗試'？你是否期望定義出錯，需要重做？ – user2357112

如果你真的要處理任何異常，請嘗試以下代碼：

import datetime 
from datetime import datetime 


class Person(object): 
    def __init__(self, name): 
     self.name = name 
     self.birthday = None 


#getName returns the name of the person   
    def getName(self): 
     return self.name   

#setBirthday sets their Birthday to a date 
    while True: 
     try: 

      def setBirthday(self): 
       while True: 
        try: 
         day = int(raw_input('Please enter the date of the month (1-31) you were born on here ->')) 
         month = int(raw_input('Please enter the month of the year (1-12) you were born on here ->')) 
         year = int(raw_input('Please enter the year you were born (19xx or 20xx) here ->')) 
         self.birthday = datetime(year, month, day) 
         print str(varPerson.getName()) + " you were born on " + str(month) + "/" + str(day) + "/" + str(year) 
        except ValueError: 
         print "better try again...return to the start of the loop" 
         continue 
        else: 
         break 
       #if day <= 0 or day >= 32: 
        #print "Please enter a number between 1 and 31. Try again." 

#getAge returns how many days old the individual is  
      def getAge(self): 
       dateNow = datetime.now() 
       dateBirth = self.birthday 
       timedelta = dateNow - dateBirth 
       print str(varPerson.getName()) + " you have been living on Earth for " + str(timedelta) 
#current date - birthdate to get specific days, timedelta 
     except: 
      pass 


varPerson = Person(raw_input('Please enter your name here ->')) 
varPerson.setBirthday() 
varPerson.getAge()

就個人而言，雖然真正的不好用...

使用此代碼片段它是一個無限循環.. – Staley

好吧，如果您刪除第一個True :,嘗試和最後一個except語句並調整這個工作的縮進。 – Staley

你的外try塊沒有。
它有一段時間沒有意義，或者直接在類定義中嘗試塊。它們必須在方法定義內。
您無法在類中的while塊中定義方法。

而不是試圖解決上述問題，請嘗試仔細研究您的代碼並確定您想要執行的操作。然後，詢問如何在StackOverflow或另一個StackExchange站點上最好地實現這個大問題的以目標爲焦點的問題，並展示迄今爲止您嘗試過的內容。

好吧，我一定很累，我完全錯過了。謝謝。我會嘗試刪除它...總是顯而易見的東西... – Staley

@Staley究竟是什麼問題？你能否確認你的問題代碼段是正確的？即使這個問題有一個機會，未來的觀衆可能會發現這個問題很有用。如果解決了您的問題，您也可以使用綠色複選標記接受我的答案。 –

你爲什麼要在循環中定義setBirthday？

while True: 
    try: 

     def setBirthday(self): 
      while True: 
       try:
