.. cfunction:: PyObject* PyList_GetSlice(PyObject *list, Py_ssize_t low, Py_ssize_t high)
- Return a list of the objects in *list* containing the objects *between*
- *low* and *high*. Return *NULL* and set an exception if unsuccessful.
- Analogous to ``list[low:high]``.

.. cfunction:: int PyList_SetSlice(PyObject *list, Py_ssize_t low, Py_ssize_t high, PyObject *itemlist)
Set the slice of *list* between *low* and *high* to the contents of
*itemlist*. Analogous to ``list[low:high] = itemlist``. The *itemlist* may
be *NULL*, indicating the assignment of an empty list (slice deletion).

Module :mod:`os`
If the locking flags :const:`O_SHLOCK` and :const:`O_EXLOCK` are present
- in the :mod:`os` module, the :func:`os.open` function provides a more
- platform-independent alternative to the :func:`lockf` and :func:`flock`
- functions.

.. function:: java_ver(release='', vendor='', vminfo=('','',''), osinfo=('','',''))
- Version interface for JPython.
+ Version interface for Jython.
Returns a tuple ``(release, vendor, vminfo, osinfo)`` with *vminfo* being a
tuple ``(vm_name, vm_release, vm_vendor)`` and *osinfo* being a tuple

and ``methodname`` is the name of a method that is defined by the object's type.
Different types define different methods. Methods of different types may have
the same name without causing ambiguity. (It is possible to define your own
- object types and methods, using *classes*, as discussed later in this tutorial.)
+ object types and methods, using *classes*, see :ref:`tut-classes`)
The method :meth:`append` shown in the example is defined for list objects; it
adds a new element at the end of the list. In this example it is equivalent to
``result = result + [b]``, but more efficient.

-This function can be called either like this: ``ask_ok('Do you really want to
-quit?')`` or like this: ``ask_ok('OK to overwrite the file?', 2)``.
+This function can be called in several ways:
+
+* giving only the mandatory argument:
+ ``ask_ok('Do you really want to quit?')``
+* giving one of the optional arguments:
+ ``ask_ok('OK to overwrite the file?', 2)``
+* or even giving all arguments:
+ ``ask_ok('OK to overwrite the file?', 2, 'Come on, only yes or no!')``
This example also introduces the :keyword:`in` keyword. This tests whether or
not a sequence contains a certain value.
