177 | ----------------------- | |
178 | ||
179 | Twitter API calls return decoded JSON. This is converted into | |
180 | a bunch of Python lists, dicts, ints, and strings. For example:: | |
7364ea65 | 181 | |
182 | x = twitter.statuses.public_timeline() | |
183 | ||
184 | # The first 'tweet' in the timeline | |
185 | x[0] | |
186 | ||
187 | # The screen name of the user who wrote the first 'tweet' | |
188 | x[0]['user']['screen_name'] | |

208 | Create a new twitter API connector. |

210 | Pass an `auth` parameter to use the credentials of a specific | |

226 | default it's twitter.com but `search.twitter.com` may be | |
227 | useful too. | |
