I seek a library that can make a simple P2P network.
This library enables you create P2P application.
THIS IS OLD, newly rewritten version 4.0.0 will be released.
- Asynchronous IO
- Pure Python code
- TCP and UDP connection
- Automatic network build
- Python3.6+
warning: Destructive change from 3.0.0
pip3 install --user p2p-python>=3.0.0
basic usage with debug tool aiomonitor.
install by pip3 install --user aiomonitor.
