Python class inheritance: AttributeError: '[SubClass]' object has no attribute 'xxx'

Question

I have the following base class and subclass:

class Event(object):
    def __init__(self, sr1=None, foobar=None):
        self.sr1 = sr1
        self.foobar          


        

Answer 1

You need to call the __init__ method of the base class from the __init__ method of the inherited class.

See here for how to do this.
