You can use this library to dump your peers.dat file from your Bitcoin client. This file keeps track of all your peers and what buckets they are currently in.
I was inspired by a blogpost, whose author wrote a similar library in Go.
I rewrote it in Python and also extracted parts of peers.dat that the Go-version was skipping, mainly bucket data.
Usage:
git clone https://github.com/asood123/bitpeers.git
pip install -r requirements.txt
python bitpeers.py --file=sample_peers.dat --output=json
