pm4py.convert.convert_to_process_tree#

pm4py.convert.convert_to_process_tree(*args: Tuple[PetriNet, Marking, Marking] | BPMN | ProcessTree) → ProcessTree[source]#

Converts an input model to a process tree.

The input models can be Petri nets (with markings) or BPMN models. For both input types, the conversion is not guaranteed to work and may raise an exception.

Return type:

ProcessTree

Parameters:

args –

If converting from a Petri net: a tuple of (PetriNet, Marking, Marking).
If converting from a BPMN or ProcessTree: a single object of the respective type.

Returns:

A ProcessTree object.

# Converts the BPMN to a process tree (through intermediate conversion to a Petri net)
