We recommend you to use Scale lib which removes spikes from measurements (spikeless_example.py).
However if you need raw data take a look at HX711 lib (example.py).
python >= 3.4
Quick code credited to Philip Whitfield "https://github.com/underdoeg/". I've only made a few modifications on the way the captured bits are processed.
There is an improved version of underdoeg's one here: "https://gist.github.com/iilxy/f8b95cd039759b18edcdfe60684a6b8f"
This project was ported from https://github.com/tatobari/hx711py to work with python3 and added functions for my needs
