        #prints status text. can be replaced with a counter probably.
        counter = counter + 1
        print(status.text)


    def on_error(self, status_code):
        if status_code == 420:
            print('420 error')
            #Ends stream in case of rate limiting

myStream.filter(track = ['Warriors'])

我是tweepy的新手,我要做的第一件事就是制作一个程序,扫描所有推文中的特定单词。一切都很顺利,直到我尝试添加一个计数器来计算该单词的实例数。无论我在哪里分配计数器,我总是在分配“错误”之前引用“UnboundLocalError:local variable”计数器。在这个程序中,我应该在哪里分配计数器?

假设上面的“不能”不在你的代码中,如果可能的话,更新你的问题以省略“”,因为它会扰乱可读性或更改为其他占位符文本。

如错误所示,您尚未为计数器分配值,方法“on_status”将尝试递增计数器,但这只是方法的局部值,而不是对象的局部值,因此失败。

def on_status(self, status):
        #prints status text. can be replaced with a counter probably.
        counter = counter + 1
        print(status.text)

您应该在 初始化 方法,然后使用self。相反,要反击。

添加

...
class MySteamListener(tweepy.StreamListener):

    def __init__(self):
        # Not sure if necessary, to make this work, but you could
        # Initialize the inherited class as well (this may work only in Python 3)
        # super().__init__()
        self.counter = 0
...

将on_状态修改为

def on_status(self, status):
        #prints status text. can be replaced with a counter probably.
        self.counter = self.counter + 1
        # Can be written as 'self.counter += 1'
        print(status.text)
