json 了解tweepy的状态对象

我一直在使用tweepy streaming API，我注意到一件事。status对象的响应不是纯粹的JSON，它还包含一些额外的信息。我的问题是：
如果我需要一条tweet的文本内容，我必须执行status.text，它位于**_json字典/ json对象**内。但是，如果我需要媒体，或者完整的文本，我必须执行status.entities['media'][0]['media_url_https']或status.extended_tweet['full_text']，尽管entities和extended_tweet都位于_json对象的另一个字典内。
为什么我们必须使用dot (.) notation来访问_json中的外部字典，而使用[] notation来访问内部字典中的值？

我理解[]表示法，但点表示法是什么意思？
状态对象：

Stackoverflow的答案here建议使用status.extended_tweet.full_text，但在我使用status.extended_tweet['full_text']之前它不起作用

JSON

主要的区别是Tweepy有一些预定义的对象（Status、User），但经常使用字典（随着数据模型的发展，它可能会更加灵活）。
例如，status.user是User对象

print(type(status.user))  # <class 'tweepy.models.User'>
print(status.user.screen_name) # beppecatanese

extended_tweet（如果存在）包含一个属性字典，例如

print(type(status.extended_tweet)) # <class 'dict'>

entities是各种对象（hashtag.media、URL等）的数组，同样 Package 在字典中

print(type(tweet.entities))  # <class 'dict'>
print(tweet.entities['urls'][0]) # First url
print(type(tweet.entities['urls'][0]))  # <class 'dict'>
print(tweet.entities['urls'][0]['expanded_url']) # expanded url of first url
