You could but it would be very bad practice and much better
to pass the object reference into Sketch.
def on_aBtn_mouseClick(self, event):
parrot.Sketch(self)
def Sketch(anObject):
....code ...
configINfo = anObject.config
Even better make the app object return the actual config
bits that parrot needs via a method:
def Sketch(anObject):
... code...
myConfigItem1,mycOnfig2 = anObject.getSketchConfig()
All of these options make both parrot and the foo object
more easily reusable and much less liable to break when
you make changes to the config data.
