Whenever you call a method, the instance is automatically provided by
Python as an argument (conventionally called "self") to the function.
So, for any arbitrary method, the call:
instance.method(arg)
is converted to:
type(instance).method(instance, arg)
hence two arguments.
My guess is that your GnomonBase __init__ method is *not* what you show
above, but (probablY) one of the following:
def __init__(bench): # oops, forgot self
# do stuff
def __init__(selfbench): # oops, forgot the comma
# do stuff
