Hi,
I have a class, where I want to store a callback function as a member
to access later:
class CallbackClass:
def setCallback(self,cb):
self.cb = cb
def callCallback(self, para):
self.cb(para)
Doing so, I get the error:
callbackFunc() takes exactly 1 parameter (2 given)
self is given as parameter this way, is it not? How can this be done?

class CBClass:

... self.cb = cb
... def call_cb(self, para):
... self.cb(para)

def trivial(arg):

c = CBClass()
c.set_cb(trivial)
c.call_cb("Hello, world")
Hello, world
Works for me. Which version of Python are you using?
