pm4py is a python library that supports (state-of-the-art) process mining algorithms in python. It is open source (licensed under GPL) and intended to be used in both academia and industry projects. pm4py is a product of the Fraunhofer Institute for Applied Information Technology.

The full documentation of pm4py can be found at http://pm4py.org/.

A very simple example, to whet your appetite:

import pm4py

if __name__ == "__main__":
    log = pm4py.read_xes('<path-to-xes-log-file.xes>')
    net, initial_marking, final_marking = pm4py.discover_petri_net_inductive(log)
    pm4py.view_petri_net(net, initial_marking, final_marking, format="svg")

pm4py can be installed on Python 3.7.x / 3.8.x / 3.9.x / 3.10.x by doing:

pip install -U pm4py
