Everything in python is a first-class, since everything is object and object is first-class. In other words, a class, a function, a method ... are assignable, referable, and so on, they use the standard data structure of the language. In java this is not true. Here is a demonstration:

Python:

class A:
  pass

def test():
  pass

print(isinstance(test,object))
a = 1
print(isinstance(a,object))
a = A()
print(isinstance(a,object))
print(isinstance(A,object))

Java:

public class Test {

    public static void main(String... args){
        int a = 1;
        System.out.println( a instanceof Object);
    }
}
