super() and order of running method in class inheritance

[akbarza]

but still, i don't know why Python in line 22 goes to child2-form1 .

That's because you read the documentation but you don't understand it.

At line 22, python will run super(child1, self).form1() . It means that it will search and call method form1() in the part of the __mro__ of self that comes after child1. This part of the __mro__ is child2 -> parent -> object. As there is a method named form1() in child2, it is this method that gets called.

hi
in the code there is super().form1() . you said

At line 22, python will run super(child1, self).form1()

. how does Python recognize this argument for super() in that line?
