Calling a base class's classmethod in Python

Question

Consider the following code:

class Base(object):

    @classmethod
    def do(cls, a):
        print cls, a

class Derived(Base):

    @classmethod
    def d         


        

Answer 1

Building on the answer from @David Z using:

super(Derived, cls).do(a)

Which can be further simplified to:

super(cls, cls).do(a)

I often use classmethods to provide alternative ways to construct my objects. In the example below I use the super functions as above for the class method load that alters the way that the objects are created:

class Base():
    
    def __init__(self,a):
        self.a = a
    
    @classmethod
    def load(cls,a):
        return cls(a=a)
    
class SubBase(Base): 

    @classmethod
    def load(cls,b):
        a = b-1
        return super(cls,cls).load(a=a)
    
base = Base.load(a=1)
print(base)
print(base.a)

sub = SubBase.load(b=3)
print(sub)
print(sub.a)

Output:

<__main__.Base object at 0x128E48B0>
1
<__main__.SubBase object at 0x128E4710>
