Quickstart

# convert from bytes to a prettier representation at the console
>>> HexBytes(b"\x03\x08wf\xbfh\xe7\x86q\xd1\xeaCj\xe0\x87\xdat\xa1'a\xda\xc0 \x01\x1a\x9e\xdd\xc4\x90\x0b\xf1;")
HexBytes('0x03087766bf68e78671d1ea436ae087da74a12761dac020011a9eddc4900bf13b')

# HexBytes accepts the hex string representation as well, ignoring case and 0x prefixes
>>> hb = HexBytes('03087766BF68E78671D1EA436AE087DA74A12761DAC020011A9EDDC4900BF13B')
HexBytes('0x03087766bf68e78671d1ea436ae087da74a12761dac020011a9eddc4900bf13b')

# get the first byte:
>>> hb[0]
3

# show how many bytes are in the value
>>> len(hb)
32

# cast back to the basic `bytes` type
>>> bytes(hb)
