[Tutor] self parameter

[Benoit Dupire]

By the way, __init__ is a very special method, because it is
automatically called when you create a new object.

To create a new object ( whose class is 'now') you have to do

a= now()

This creates a new object and calls the __init__ method, to initialize
the instance variables (ie. the variables within the object 'a', ie.
self.year, self.month, etc..)

usually , if you want to call a method you have to do:

<name of the object>.<name of the method> ( <parameters>)

so here it would be:
a.__init__( )

Note that  this calls the __init__ method substituting  'self' (the
first parameter of the method) with 'a'.


Now on the 'design point-of-view', there is little interest in having a
class 'now'. Why do you want to do objects ?
I think a simple function should do the job, storing your time values in
a list.
