The Python Language Reference Manual

This manual is the definitive language reference for Python. It describes the syntax of Python and its built-in datatypes in depth.

Python is an interpreted object-oriented programming language, suitable for rapid application development and scripting. Python's syntax emphasizes readability, which reduces the cost of program maintenance.

This manual covers advanced topics, and is suitable for readers who need to be familiar with the details and rules of the Python language and its object system. A tutorial suitable for those new to Python is available in the companion volume "An Introduction to Python". The standard Python library is documented separately in "The Python Library Reference Manual".
