python abstract base classes, difference between mixin & abstract method -


the following table shows varying abstract base classes used on python. however, bit confused (in context)

what difference between abstract methods column , mixin methods column. 1 optionally implemented , other not?

i've been mulling on , every 1 of "theories" doesn't seem right.

reference


enter image description here

anything in abstract methods column, have implement yourself. abc provides default implementations of methods in mixin methods column, implemented in terms of methods have write.
