We have the code below in a script module that converts Ignition-specific objects to native Python lists and dicts. We pass the Ignition object to the propertyToPython function, and get back Python lists and/or dicts.
def _isDictLikeObject(value):
return 'iteritems' in dir(value)
def _isListLikeObject(value):
return 'append' in dir(value)
def dictLikeObjectToDict(dictLikeObject):
pyDict = {}
for key, item in dict(dictLikeObject).iteritems():
item = propertyToPython(item)
pyDict[key] = item
return pyDict
def listLikeObjectToList(listLikeObject):
pyList = []
for item in list(listLikeObject):
item = propertyToPython(item)
pyList.append(item)
return pyList
def propertyToPython(property):
"""
Accepts a value, object, or array property that might be
encoded as an Ignition ObjectWrapper or ArrayWrapper and
returns the property as Python dicts and lists.
"""
if _isDictLikeObject(property):
property = dictLikeObjectToDict(property)
elif _isListLikeObject(property):
property = listLikeObjectToList(property)
return property
