The important thing and aspect characters #, !, =, and : are written with a previous backslash to ensure that they are properly loaded.

Observe that super() is applied as part of the binding course of for particular dotted attribute lookups resembling tremendous().__getitem__(determine). It does so by implementing its own __getattribute__() approach for looking courses in a predictable order that helps cooperative various inheritance.
