def _init_attribs(self): (source)

A method to define extra attributes that will be set after initialization.

Note
Most attributes don't need a special value at initialization (if they use None as default for instance), in those cases, avoid overriding this method by declaring them as class variable. Override this method only if you have to initialize an attribute value to a mutable object.
