This is an example of a module level function.

Function parameters should be documented in the ``Args`` section. The name
of each parameter is required. The type and description of each parameter
is optional, but should be included if not obvious.

If \*args or \*\*kwargs are accepted,
they should be listed as ``*args`` and ``**kwargs``.

The format for a parameter is::

    name (type): description
        The description may span multiple lines. Following
        lines should be indented. The "(type)" is optional.

        Multiple paragraphs are supported in parameter
        descriptions.

Args:
    param1 (int): The first parameter.
    param2 (:obj:`str`, optional): The second parameter. Defaults to None.
        Second line of description should be indented.
    *args: Variable length argument list.
    **kwargs: Arbitrary keyword arguments.

Returns:
    bool: True if successful, False otherwise.

    The return type is optional and may be specified at the beginning of
    the ``Returns`` section followed by a colon.

    The ``Returns`` section may span multiple lines and paragraphs.
    Following lines should be indented to match the first line.

    The ``Returns`` section supports any reStructuredText formatting,
    including literal blocks::

        {
            'param1': param1,
            'param2': param2
        }

Raises:
    AttributeError: The ``Raises`` section is a list of all exceptions
        that are relevant to the interface.
    ValueError: If `param2` is equal to `param1`.

Yields:
    int: The next number in the range of 0 to `n` - 1.

Examples:
    Example 1

    >>> print([i for i in example_generator(4)])
    [0, 1, 2, 3]

    Example 2

    >>> # comments are ignored
    >>> x = 12
    >>> x
    12
    >>> if x == 13:
    ...     print("yes")
    ... else:
    ...     print("no")
    ...     print("NO")
    ...     print("NO!!!")
    ...
    no
    NO
    NO!!!
