Bit is Python's fastest <https://ofek.github.io/bit/guide/intro.html#why-bit>_ Bitcoin library and was designed from the beginning to feel intuitive, be effortless to use, and have readable source code. It is heavily inspired by Requests <https://github.com/requests/requests>_ and Keras <https://github.com/keras-team/keras>_.

Bit is so easy to use, in fact, you can do this:

.. code-block:: python

>>> from bit import Key
>>>
>>> my_key = Key(...)
>>> my_key.get_balance('usd')
'12.51'
>>>
>>> # Let's donate!
>>> outputs = [
>>>     # Wikileaks
>>>     ('1HB5XMLmzFVj8ALj6mfBsbifRoD4miY36v', 0.0035, 'btc'),
>>>     # Internet Archive
>>>     ('1Archive1n2C579dMsAu3iC6tWzuQJz8dN', 190, 'jpy'),
>>>     # The Pirate Bay
>>>     ('129TQVAroeehD9fZpzK51NdZGQT4TqifbG', 3, 'eur'),
>>>     # xkcd
>>>     ('14Tr4HaKkKuC1Lmpr2YMAuYVZRWqAdRTcr', 2.5, 'cad')
>>> ]
>>>
>>> my_key.send(outputs)
'9f59f5c6757ec46fdc7440acbeb3920e614c8d1d247ac174eb6781b832710c1c'
