The minimalist yet fully featured Twitter API class.
-
+
Get RESTful data by accessing members of this class. The result
is decoded python objects (lists and dicts).
The Twitter API is documented here:
- http://groups.google.com/group/twitter-development-talk/web/api-documentation
-
+
+ http://apiwiki.twitter.com/
+ http://groups.google.com/group/twitter-development-talk/web/api-documentation
+
Examples::
-
- twitter = Twitter("hello@foo.com", "password123")
-
+
+ twitter = Twitter(
+ auth=OAuth(token, token_key, con_secret, con_secret_key)))
+
# Get the public timeline
twitter.statuses.public_timeline()
-
+
# Get a particular friend's timeline
twitter.statuses.friends_timeline(id="billybob")
-
+
# Also supported (but totally weird)
twitter.statuses.friends_timeline.billybob()
-
+
# Send a direct message
twitter.direct_messages.new(
user="billybob",
text="I think yer swell!")
- Using the data returned::
- Twitter API calls return decoded JSON. This is converted into
- a bunch of Python lists, dicts, ints, and strings. For example,
+ Searching Twitter::
+
+ twitter_search = Twitter(domain="search.twitter.com")
+
+ # Find the latest search trends
+ twitter_search.trends()
+
+ # Search for the latest News on #gaza
+ twitter_search.search(q="#gaza")
+
+
+ Using the data returned
+ -----------------------
+
+ Twitter API calls return decoded JSON. This is converted into
+ a bunch of Python lists, dicts, ints, and strings. For example::
x = twitter.statuses.public_timeline()
# The screen name of the user who wrote the first 'tweet'
x[0]['user']['screen_name']
