Python built-ins reference

Python comes with a number of built-in functions and classes.

The built-in classes include data types that would normally be considered part of the "core" of a language, such as numbers and lists. For these types, the Python language core defines the form of literals and places some constraints on their semantics, but does not fully define the semantics.

The built-ins also include functions and exceptions --- objects that can be used by all Python code without the need of an import statement. Some of these are defined by the core language, but many are not essential for the core semantics and are only described here.

In addition to the built-ins, Python provides an extensive importable standard library, see The Python standard library.
