The difference between Python parent.__init () and super (Child, self)

What the Super function does

def Supper (CLS, inst):     = Inst.__class__. MRO ()    return mro[mro.index (CLS) + 1]

Inst generating a list of parent classes

Finds the CLS index from the list and returns its next index

Assume

MRO = [A,b,c]

CLS = b

Then the CLS index is 1

Returns the next index, which is mro[2], c

MRO process is method Resolution Order

The Inst method returns all the parent classes of the

Order is

Suppose A is a base class, b,c are subclasses of a, D inherits B and C (inheritance order is b,c)

So the MRO of D is returning

[D,b,c,a]

The use of the Super (D,self) method for D returns the B
