For more details, see the Python documentation for super().

I really still didn't understand why call super() in Sneaky and Agile :( MRO means: Method resolution order:
- Childclass
- Parentclass
- builtins.object So, if python doesn't find it in the childclass then it goes to the parent class. If Python does not find it in the Child/Parent class then python should find it in the builtins.object class.
I read the python doc but still didn't understand:( Could you please provide examples so that I can understand it?:)

__init__method of each class. But here's what you'll see if you do that and instantiate an object of the class that has the multiple inherittance of(Sneaky, Agile, Character). "Sneaky" calls super, and the MRO directs it to Agile, which also calls super, which directs it to Character. So the printed messages will show that the inits for Character, then Agile, then Sneaky all ran, and completed in that order.MoatazBellah Ghobashy
