java - python - another class inside constructor -

i'm new python , i'm having hard time understanding how can following in python (e.g how in java)

class person{   private string name;  private address address;   public person(string xyz, address a) {     this.name = xyz;     this.address = a; }   ....  } 

i don’t know why think there class inside constructor, above java in python:

class person (object):     def __init__ (self, xyz, a):         self.name = xyz         self.address = 

as dynamically typed language, python not need know types when code compiles. instead, dynamically creates objects, , adds properties whenever needed. allows not add instance fields in initializer not declared before, allows add things after object created:

x = person("poke", "my address") x.phonenumber = "012345679"
