Finding Doctests in Modules Not Written in Python
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
DocTestFinder can also find doctests in most modules not written in Python.
We'll use builtins as an example, since it almost certainly isn't written in
plain ol' Python and is guaranteed to be available.

    >>> import builtins
    >>> tests = doctest.DocTestFinder().find(builtins)
    >>> 790 < len(tests) < 800 # approximate number of objects with docstrings
    True
    >>> real_tests = [t for t in tests if len(t.examples) > 0]
    >>> len(real_tests) # objects that actually have doctests
    8
    >>> for t in real_tests:
    ...     print('{}  {}'.format(len(t.examples), t.name))
    ...
    1  builtins.bin
    3  builtins.float.as_integer_ratio
    2  builtins.float.fromhex
    2  builtins.float.hex
    1  builtins.hex
    1  builtins.int
    2  builtins.int.bit_length
    1  builtins.oct

Note here that 'bin', 'oct', and 'hex' are functions; 'float.as_integer_ratio',
'float.hex', and 'int.bit_length' are methods; 'float.fromhex' is a classmethod,
and 'int' is a type.
