bitfields 0.1

Bit manipulation library that allows binary number indexing and bit field construction.

Python Bit Fields provides simple bit manipulation and bit field construction in Python. Everything is built on the int type so no number functionality is lost, while making it possible to index and slice binary numbers like strings.

---

Basic usage:

>>> num = Bits(20)
>>> num
Bits(0b10100)
>>> num * 3
Bits(0b111100)
>>> num[:4]
Bits(0b1010)
>>> num.bit_length()
5
>>> num.join(0b101)
Bits(0b10100101)

Color Guard also supports conversion to and from other Python data types.

>>> Bits.from_binary("111101001101")
Bits(0b111101001101)
>>> Bits.from_hex("abc123")
Bits(0b101010111100000100100011)
>>> Bits.from_bytes(b"abc")
Bits(0b11000010110001001100011)

>>> bytes(Bits(367))
b'\x01o'
>>> int(Bits(0b1011010))
90
>>> list(Bits(367))
[1, 0, 1, 1, 0, 1, 1, 1, 1]
