hexbytes package
Quickstart
Install with:
pip install hexbytes
Example HexBytes
usage:
>>> from hexbytes import HexBytes
# 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)
b"\x03\x08wf\xbfh\xe7\x86q\xd1\xeaCj\xe0\x87\xdat\xa1'a\xda\xc0 \x01\x1a\x9e\xdd\xc4\x90\x0b\xf1;"
HexBytes
- class hexbytes.main.HexBytes(val: Union[bool, bytearray, bytes, int, str, memoryview])
Bases:
bytes
HexBytes is a very thin wrapper around the python built-in
bytes
class.- It has these three changes:
Accepts more initializing values, like hex strings, non-negative integers, and booleans
Returns hex with prefix ‘0x’ from
HexBytes.hex()
The representation at console is in hex
