Support for the :keyword:`with` statement was added.
Provides an overriding level *lvl* for all loggers which takes precedence over
the logger's own level. When the need arises to temporarily throttle logging
- output down across the whole application, this function can be useful.
+ output down across the whole application, this function can be useful. Its
+ effect is to disable all logging calls of severity *lvl* and below, so that
+ if you call it with a value of INFO, then all INFO and DEBUG events would be
+ discarded, whereas those of severity WARNING and above would be processed
+ according to the logger's effective level.
.. function:: addLevelName(lvl, levelName)
>>> 3*a[:3] + ['Boo!']
['spam', 'eggs', 100, 'spam', 'eggs', 100, 'spam', 'eggs', 100, 'Boo!']
+All slice operations return a new list containing the requested elements. This
+means that the following slice returns a shallow copy of the list *a*::
+
+ >>> a[:]
+ ['spam', 'eggs', 100, 1234]
+
Unlike strings, which are *immutable*, it is possible to change individual
elements of a list::
