Get Python Language Reference

Python is a free, open-source programming language that is available for everyone to use.

Python is developed under an OSI-approved open source license, making it freely usable and distributable, even for commercial use. Python's license is administered by the Python Software Foundation.

The books are good to introduce you the language, with examples. You should definitely read them if you have time. Finally, when you're developing an application, you can also learn by reading the source code, exploring where the code is going and what is happening.

Welcome to Python.org.

Python has a built-in help() function that can access this information and prints the results. For example, to see the documentation of the built-in len function, you can do the following: In [1]: help(len) Help on built-in function len in module builtins: len(...)

Python.org is the holy grail of all things Python as it hosts the official documentation of the Python programming language.

In order to cite a programming language like Python, you can cite a reference manual. This is the generally preferred way how to cite a programming language. Other option is to cite a standard textbook or popular book. You should always consider what reference will provide the most suitable information for you readers.

A Python program accesses data values through references. A reference is a name that refers to the specific location in memory of a value (object). References take the form of variables, attributes, and items.

The Python interpreter and the extensive standard library are freely available in source or binary form for all major platforms from the Python web site, https://.python.org/, and may be freely distributed.
