OK
class BaseClass(object):
def __init__(self, a, b, c, d):
self.a = a
self.b = b
self.c = c
self.d = d
class NewClass(BaseClass):
def __init__(self):
super(NewClass, self).__init__(new)
self.new = new
print self.new
class PreviousClass:
def __init__(self, a, b, c, d, new):
self.a = a
self.b = b
self.c = c
self.d = d
self.new = new
print self.new
if __name__ == "__main__":
A = PreviousClass(1, 2, 3, 4, 5)
B = NewClass(1, 2, 3, 4, 5)
$ python test.py
Traceback (most recent call last):
File "model_data.py", line 29, in <module>
B = NewClass(1, 2, 3, 4, 5)
TypeError: __init__() takes exactly 1 argument (6 given)
So NewClass is my attempt to implement what I was shown and
PreviousClass was how I was originally solving the issue, i.e. I
wouldn't inherit the BaseClass.
