Python＆Tweepy - 如何比较和更改时间。

Question

我想创建一些基于Twitter处理集的其他一些代码的约束。

我有下面的代码的问题，因为：

TypeError: can't compare datetime.datetime to str 

看来，即使我已经改变LAST_POST为datetime对象最初，当我把它比作datetime.datetime.today（）是转换为字符串。是的，我已检查确保Last_post正确转换。我不确定发生了什么事。帮帮我？

for handle in handles: 
    try: 
     user = api.get_user(handle) 
     #print json.dumps(user, indent = 4) 
     verified = user["verified"] 
     name = user['name'] 
     language = user['lang'] 
     follower_count = user['followers_count'] 
     try: 
      last_post = user['status']['created_at'] 
      last_post = datetime.strptime(last_post, '%a %b %d %H:%M:%S +0000 %Y') 
     except: 
      last_post = "User has not posted ever" 
     location = user['location'] 

     location_ch = location_check(location) 

     if location_ch is not "United States": 
      location_output.append(False) 
     else: 
      location_output.append(True) 

     new_sum.append(follower_count) 

     if language is not "en": 
      lang_output.append(False) 
     else: 
      lang_output.append(True) 

     if datetime.datetime.today() - datetime.timedelta(days=30) > last_post: 
      recency.append(False) 
     else: 
      recency.append(True)

我认为你需要向Twitter的日期转换为时间戳：

import time 

ts = time.strftime('%Y-%m-%d %H:%M:%S', time.strptime(tweet['created_at'],'%a %b %d %H:%M:%S +0000 %Y'))
