A wrapper around the Trello API written in Python. Each Trello object is represented by a corresponding Python object. The attributes of these objects are cached, but the child objects are not. This can possibly be improved when the API allows for notification subscriptions; this would allow caching (assuming a connection was available to invalidate the cache as appropriate).

I've created a Trello Board for feature requests, discussion and some development tracking.

Install

pip install py-trello

Usage

from trello import TrelloClient

client = TrelloClient(
    api_key='your-key',
    api_secret='your-secret',
    token='your-oauth-token-key',
    token_secret='your-oauth-token-secret'
)

Where token and token_secret come from the 3-legged OAuth process and api_key and api_secret are your Trello API credentials that are (generated here).

To use without 3-legged OAuth, use only api_key and api_secret on client.

Working with boards

all_boards = client.list_boards()
last_board = all_boards[-1]
print(last_board.name)

working with board lists and cards

all_boards = client.list_boards()
last_board = all_boards[-1]
last_board.list_lists()
my_list = last_board.get_list(list_id)

for card in my_list.list_cards():
    print(card.name)

Getting your Trello OAuth Token

Make sure the following environment variables are set:

• TRELLO_API_KEY
• TRELLO_API_SECRET

These are obtained from the link mentioned above.

TRELLO_EXPIRATION is optional. Set it to a string such as 'never' or '1day'. Trello's default OAuth Token expiration is 30 days.

Default permissions are read/write.

More info on setting the expiration here: https://trello.com/docs/gettingstarted/#getting-a-token-from-a-user

Run

python ./trello/util.py

Required Python modules

Found in requirements.txt

Tests

To run the tests, run python -m unittest discover. Four environment variables must be set:

• TRELLO_API_KEY: your Trello API key
• TRELLO_TOKEN: your Trello OAuth token
• TRELLO_TEST_BOARD_COUNT: the number of boards in your Trello account
• TRELLO_TEST_BOARD_NAME: name of the board to test card manipulation on. Must be unique, or the first match will be used

To run tests across various Python versions, tox is supported. Install it and simply run tox from the py-trello directory.
