 ``ipipe`` supports "pipeline expressions", which is something resembling Unix
 pipes. An example is::
 
-    py> ienv | isort("key.lower()")
+    >>> ienv | isort("key.lower()")
 
 This gives a listing of all environment variables sorted by name.

   for example::

       ...
 
   Note: The expression strings passed to ``ifilter()`` and ``isort()`` can
   refer to the object to be filtered or sorted via the variable ``_`` and to any
   of the attributes of the object, i.e.::
 
-      py> sys.modules | ifilter("_.value is not None") | isort("_.key.lower()")
+      >>> sys.modules | ifilter("_.value is not None") | isort("_.key.lower()")
 
   does the same as::
 
-      py> sys.modules | ifilter("value is not None") | isort("key.lower()")
+      >>> sys.modules | ifilter("value is not None") | isort("key.lower()")
 
   In addition to expression strings, it's possible to pass callables (taking
   the object as an argument) to ``ifilter()``, ``isort()`` and ``ieval()``::
 
-      py> sys | ifilter(lambda _:isinstance(_.value, int)) \
+      >>> sys | ifilter(lambda _:isinstance(_.value, int)) \
       ...     | ieval(lambda _: (_.key, hex(_.value))) | idump
