4 The Python Language Reference
5 #################################
10 This reference manual describes the syntax and "core semantics" of the
11 language. It is terse, but attempts to be exact and complete. The semantics of
12 non-essential built-in object types and of the built-in functions and modules
13 are described in :ref:`library-index`. For an informal introduction to the
14 language, see :ref:`tutorial-index`. For C or C++ programmers, two additional
15 manuals exist: :ref:`extending-index` describes the high-level picture of how to
16 write a Python extension module, and the :ref:`c-api-index` describes the
17 interfaces available to C/C++ programmers in detail.
