For a recursive function we can do:
def f(i): if i<0: return print i f(i-1) f(10) However is there a way to do the following thing?
class A: # do something some_func(A) # ...

If I understand your question correctly, you should be able to reference class A within class A by putting the type annotation in quotes. This is called forward reference.
When an object of some class has an attribute value of that same class, it is a recursive object.
__class__ # Output: <class 'type'> Thus, the above code shows that the Human class and every other class in Python are objects of the class type . This type is a class and is different from the type function that returns the type of object.
Python also accepts function recursion, which means a defined function can call itself. Recursion is a common mathematical and programming concept. It means that a function calls itself. This has the benefit of meaning that you can loop through data to reach a result.

class A: # do something def some_func(self, a: 'A') # ... See ref below

In Python you cannot reference the class in the class body, although in languages like Ruby you can do it.
In Python instead you can use a class decorator but that will be called once the class has initialized. Another way could be to use metaclass but it depends on what you are trying to achieve.
