Bit: Bitcoin made easy.

Version 0.7.2.

---

Bit is Python’s fastest 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 and Keras.

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

>>> 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'

Here is the transaction https://blockchain.info/tx/9f59f5c6757ec46fdc7440acbeb3920e614c8d1d247ac174eb6781b832710c1c.
