Epydemic is a Python library that implements simulations of epidemic (and other) processes on networks, supporting compartmental disease models and providingstochastic simulations for infectious disease research. It is freely available through PyPI and the source code can be accessed on GitHub. As a Python library, it is designed for researchers and developers, with comprehensive documentation, installation instructions, and example models available through the Read the Docs website, making it straightforward to learn and extend for custom epidemic simulations.
