Question

How to get attribute to subclass?
I mean the part age=age

def method(name='thomas', age=27):
   submethod(age=age)

Answer 1

I’m not totally sure what you mean by this code, is the submethod abstract?

Anyway, you’re missing self, that’s not a method. This should work:

def method(self, name='Thomas', age=27):
  self.submethod(name, age)

If the submethod argument is keyword only, you could rename the local argument value for clarity:

def method(self, name='Thomas', age=27):
  the_age = age
  self.submethod(name, age=the_age)

Or just don’t, keyword names don’t collide with local variables anyway, so your original code works once you add the self:

def method(self, name='Thomas', age=27):
  self.submethod(name, age=age)
