    Point(x=11, y=22)
 
 Since a named tuple is a regular Python class, it is easy to add or change
-functionality.  For example, the display format can be changed by overriding
-the :meth:`__repr__` method:
+functionality with a subclass.  Here is how to add a calculated field and
+a fixed-width print format::
 
-::
+    >>> class Point(namedtuple('Point', 'x y')):
+        @property
+        def hypot(self):
+            return (self.x ** 2 + self.y ** 2) ** 0.5
+        def __repr__(self):
+            return 'Point(x=%.3f, y=%.3f, hypot=%.3f)' % (self.x, self.y, self.hypot)
 
-    >>> Point = namedtuple('Point', 'x y')
-    >>> Point.__repr__ = lambda self: 'Point(%.3f, %.3f)' % self
-    >>> Point(x=11, y=22)
-    Point(11.000, 22.000)
+    >>> print Point(3, 4),'\n', Point(2, 5), '\n', Point(9./7, 6)
+    Point(x=3.000, y=4.000, hypot=5.000) 
+    Point(x=2.000, y=5.000, hypot=5.385) 
+    Point(x=1.286, y=6.000, hypot=6.136)
+
+Another use for subclassing is to replace performance critcal methods with
+faster versions that bypass error-checking and localize variable access::
+
+    >>> class Point(namedtuple('Point', 'x y')):
+        _make = classmethod(tuple.__new__)
+        def _replace(self, _map=map, **kwds):

 and customizing it with :meth:`_replace`:

    function does nothing.
 
 
+.. function:: reload(module)
+
+   Reload a previously imported *module*.  The argument must be a module object, so
+   it must have been successfully imported before.  This is useful if you have
+   edited the module source file using an external editor and want to try out the
+   new version without leaving the Python interpreter.  The return value is the
+   module object (the same as the *module* argument).
+
+   When ``reload(module)`` is executed:
+
+   * Python modules' code is recompiled and the module-level code reexecuted,
+     defining a new set of objects which are bound to names in the module's
+     dictionary.  The ``init`` function of extension modules is not called a second
+     time.
+
+   * As with all other objects in Python the old objects are only reclaimed after
+     their reference counts drop to zero.
+
+   * The names in the module namespace are updated to point to any new or changed
+     objects.
+
+   * Other references to the old objects (such as names external to the module) are
+     not rebound to refer to the new objects and must be updated in each namespace
+     where they occur if that is desired.
+
+   There are a number of other caveats:
+
+   If a module is syntactically correct but its initialization fails, the first
+   :keyword:`import` statement for it does not bind its name locally, but does
+   store a (partially initialized) module object in ``sys.modules``.  To reload the
+   module you must first :keyword:`import` it again (this will bind the name to the
+   partially initialized module object) before you can :func:`reload` it.
+
+   When a module is reloaded, its dictionary (containing the module's global
+   variables) is retained.  Redefinitions of names will override the old
+   definitions, so this is generally not a problem.  If the new version of a module
+   does not define a name that was defined by the old version, the old definition
+   remains.  This feature can be used to the module's advantage if it maintains a
+   global table or cache of objects --- with a :keyword:`try` statement it can test
+   for the table's presence and skip its initialization if desired::
+
+      try:
+          cache
+      except NameError:
+          cache = {}
+
+   It is legal though generally not very useful to reload built-in or dynamically
+   loaded modules, except for :mod:`sys`, :mod:`__main__` and :mod:`__builtin__`.
+   In many cases, however, extension modules are not designed to be initialized
+   more than once, and may fail in arbitrary ways when reloaded.
+
+   If a module imports objects from another module using :keyword:`from` ...
+   :keyword:`import` ..., calling :func:`reload` for the other module does not
+   redefine the objects imported from it --- one way around this is to re-execute
+   the :keyword:`from` statement, another is to use :keyword:`import` and qualified
+   names (*module*.*name*) instead.
+
+   If a module instantiates instances of a class, reloading the module that defines
+   the class does not affect the method definitions of the instances --- they
+   continue to use the old class definition.  The same is true for derived classes.
+
+
 The following constants with integer values, defined in this module, are used to
 indicate the search result of :func:`find_module`.

+Intermezzo: Coding Style
+========================
+
+.. sectionauthor:: Georg Brandl <georg@python.org>
+.. index:: pair: coding; style
+
+Now that you are about to write longer, more complex pieces of Python, it is a
+good time to talk about *coding style*.  Most languages can be written (or more
+concise, *formatted*) in different styles; some are more readable than others.
+Making it easy for others to read your code is always a good idea, and adopting
+a nice coding style helps tremendously for that.
+
+For Python, :pep:`8` has emerged as the style guide that most projects adher to;
+it promotes a very readable and eye-pleasing coding style.  Every Python
+developer should read it at some point; here are the most important points
+extracted for you:
+
+* Use 4-space indentation, and no tabs.
+
+  4 spaces are a good compromise between small indentation (allows greater
+  nesting depth) and large indentation (easier to read).  Tabs introduce
+  confusion, and are best left out.
+
+* Wrap lines so that they don't exceed 79 characters.
+
+  This helps users with small displays and makes it possible to have several
+  code files side-by-side on larger displays.
+
+* Use blank lines to separate functions and classes, and larger blocks of
+  code inside functions.
+
+* When possible, put comments on a line of their own.
+
+* Use docstrings.
+
+* Use spaces around operators and after commas, but not directly inside
+  bracketing constructs: ``a = f(1, 2) + g(3, 4)``.
+
+* Name your classes and functions consistently; the convention is to use
+  ``CamelCase`` for classes and ``lower_case_with_underscores`` for functions
+  and methods.  Always use ``self`` as the name for the first method argument.
+
+* Don't use fancy encodings if your code is meant to be used in international
+  environments.  Plain ASCII works best in any case.
+
