2 days ago · 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.

This section contains a Python reference documentation. Track your progress - it's free! Well organized and easy to understand Web building tutorials with lots of examples of how to use HTML, CSS, JavaScript, SQL, Python, PHP, Bootstrap, Java, XML and more.

In order to cite a programming language, a possible way is to cite the reference manual, including the version of the language you use (your approach might no longer work with the version of Python available in 20 years ...). For instance, you can have a citation like: Python Software Foundation. Python Language Reference, version 2.7.

Python supports modules and packages, which encourages program modularity and code reuse. The Python interpreter and the extensive standard library are available in source or binary form without charge for all major platforms, and can be freely distributed. This reference manual describes the syntax and “core semantics” of the language.
