Hi, I made a python3 library called bitpeer.py with these features:

• Bitcoin protocol data serialization / deserialization
• Customizable clients for single node connections
• Network support for different coins (bitcoin, namecoin, litecoin)
• DNS seed bootstrap
• Multiple connections
• Mempool and transaction broadcast
• Automatic syncronization with storage capabilities (the storage abstraction allows different storage types)
• Storage types: shelve and memory
• Peer reconnection handling

The library is available on github (https://github.com/dakk/bitpeer.py) and pypi (pip3 install bitpeer.py).
