NLTK Twitter client
|
||
|
|
|
||
|
|
This module offers methods for collecting and processing Tweets. Most of the
|
||
|
|
functionality depends on access to the Twitter APIs, and this is handled via
|
||
|
|
the third party Twython library.
|
||
|
|
|
||
|
|
If one of the methods below returns an integer, it is probably a `Twitter
|
||
|
|
error code <https://dev.twitter.com/overview/api/response-codes>`_. For
|
||
|
|
example, the response of '420' means that you have reached the limit of the
|
||
|
|
requests you can currently make to the Twitter API. Currently, `rate limits
|
||
|
|
for the search API <https://dev.twitter.com/rest/public/rate-limiting>`_ are
|
||
|
|
divided into 15 minute windows.
