How to I stream language tweets?

[raomanohar]

Hi,

I am trying to stream Portuguese tweets and perform sentiment analysis on those

If I pass in a stream.filter("lang='pt') its not working,

If I use a tweepy.Cursor then I am able to filter tweets based on language but those are not realtime tweets.

I am looking to stream Tweets made in Portuguese and perform sentiment analysis please help

There's syntactical mistakes with how you're passing the keyword argument, but the name of the kwarg for Stream.filter is languages anyway:

tweepy/tweepy/streaming.py

Lines 432 to 433 in cc3c8e7

	def filter(self, follow=None, track=None, is_async=False, locations=None,
	stall_warnings=False, languages=None, encoding='utf8', filter_level=None):

It accepts a list of languages, so you would provide it like so: stream.filter(languages=["pt"]).
However, note, you'll still need to input either a list of user IDs to follow, using follow; a list of keywords to track, using track; or a list of locations to track, using locations.
