파이썬 2.7 datetime 형식의 파이썬 3.6 datetime 개체

Question

나는 파이썬 3.6과 호환되는 파이썬 2.7 코드를 작성하고있다.

코드는 파이썬 2.7에서 잘 작동하지만 난 파이썬 3.6에서 날짜 문제를 점점 오전 :

def insert_event(self, subject_event): 
     for x in range (0,self.event_count): 
      if self.events[x].time <= subject_event.time: 


TypeError: '<=' not supported between instances of 'type' and 'datetime.datetime' 

은 내가이있어 코드를 디버깅 않은 경우 :

<event.Event object at 0x7f89b7cdb908> 
(Pdb) print (subject_event.time)

파이썬 3.6에서 날짜 시간이 변경 되었습니까?

Answer 1

TypeError의 이유는 다른 유형의 객체가 인데 비해서는 (숫자 유형과 같은 일부 예외가 있음)입니다. 파이썬 2에서는 서로 다른 유형의 객체를 비교하는 것이 합법적입니다.

자세한 내용은 What's new in Python 3을 확인하십시오.

실제로 계급 및 인스턴스가 아닌 datetime인스턴스을 비교하려고합니다.
