__init__() not called automatically

[Sri Charan]

The compiler also calls the default arguement constructor
automatically, if such a constructor is provided for the base
class(es); but, this becomes a special case of what has been said by
Andrew Koenig.

So, it is NOT just the no arguement constructor that is automatically
called; note that the default arguement constructor is kinda put in
place because sometimes, the user may call the constructor with no
arguements, while the object actually needs some values for proper
construction.
