The Python Language Reference

This reference manual describes the syntax and "core semantics" of the
language. It is terse, but attempts to be exact and complete. The
semantics of non-essential built-in object types and of the built-in
functions and modules are described in *The Python Standard Library*.
For an informal introduction to the language, see *The Python
Tutorial*. For C or C++ programmers, two additional manuals exist:
*Extending and Embedding the Python Interpreter* describes the high-
level picture of how to write a Python extension module, and the
*Python/C API Reference Manual* describes the interfaces available to
C/C++ programmers in detail.
