title: Private methods in Python
body: <p>I would like to have a function in my class, which I am going to use only inside methods of this class. I will not call it outside the implementations of these methods. In C++, I would use a method declared in the private section of the class. What is the best way to implement such a function in Python?</p>
  <p>I am thinking of using a static decorator for this case. Can I use a function without any decorators and the <code>self</code> word?</p>
