class TwitterListener(StreamListener):
def __init__(self):
pass
def on_data(self, data):
print(data.text)
这是我希望我的听众做的一个例子。我只想打印通过的推文的文本，但是当尝试这样做时，出现以下错误：
File "test 2.0.py", line 72, in on_data
print(data.text)
AttributeError: 'str' object has no attribute 'text'
很显然，我的tweet是作为字符串而不是tweet对象传递的。我仍然可以打印整个数据，它将像预期的那样（像对象一样）给出它，但是实际上，它只是一个看起来像对象的字符串

那看起来像一个json对象，所以尝试：
import json
class TwitterListener(StreamListener):
def __init__(self):
pass
def on_data(self, data):
deserialized = json.loads(data)
print(deserialized['text'])
