#### The __doc__ attribute

Each Python object (functions, classes, variables,...) provides (if programmer has filled it) a short documentation which describes its features. You can access it with commands like print myobject.__doc__. You can provide a documentation for your own objects (functions for example) in the body of their definition as a string surrounded by three double-quotes:

    >>> def myfunc():
    ...    """'myfunc' documentation."""
    ...    pass
    ...
    >>> print myfunc.__doc__
    'myfunc' documentation.
