Deprecated Deprecated
========== ==========
This section covers various APIs and other features that have been deprecated
in Python 3.4, and will be removed in Python 3.5 or later. In most (but not
all) cases, using the deprecated APIs will produce a :exc:`DeprecationWarning`
when the interpreter is run with deprecation warnings enabled (for example, by
using ``-Wd``).
