pm4py.objects.powl.parser.parse_powl_model_string(powl_string, level=0) → POWL[source]#

Parse a POWL model from a string representation of the process model (with the same format as the __repr__ and __str__ methods of the POWL model)

Minimum Viable Example:

from pm4py.objects.powl.parser import parse_powl_model_string

powl_model = parse_powl_model_string(‘PO=(nodes={ NODE1, NODE2, NODE3 }, order={ NODE1–>NODE2 }’) print(powl_model)

Parameters#

powl_string: POWL model expressed as a string (__repr__ of the POWL model)

Returns#

powl_model: POWL model
