Outline of the Python programming language

The following outline is provided as an overview of and topical guide to Python:

Python is a general-purpose, interpreted, object-oriented, functional, multi-paradigm, and dynamically typed programming language known for its emphasis on code readability

and broad standard library. Python was created by Guido van Rossum and first released in 1991. It emphasizes code readability and developer productivity.

What type of language is Python?

• Programming language — artificial language designed to communicate instructions to a machine.
• Object-oriented programming — built primarily around objects and classes.
• Functional programming — supports functions as first-class objects.
• Scripting language — often used for automation and small programs.
• General-purpose programming language — designed for a wide variety of application domains.
• Dynamically typed — type checking occurs at runtime.
• Interpreted language — code is executed by an interpreter.
• Multi-paradigm — supports procedural, object-oriented, and functional programming.

History of Python

• ABC (programming language) – precursor to Python
• Python was started by Guido van Rossum in 1989 and first released in 1991.
• Python 2 — major version released in 2000, officially retired in 2020.
• Python 3 — released in 2008

General Python concepts

Issues and limitations

• Performance — generally slower than many compiled languages such as C or Java, can be mitigated by C extensions or JIT compilers (PyPy).
• Global interpreter lock — limits parallel CPU-bound threads in CPython
• Memory consumption — high memory use compared to some lower-level languages
• Version compatibility — Python 2 vs Python 3 differences caused migration issues

Python implementations

• CPython — reference implementation in C
• IronPython — Python for .NET
• Jython — Python for the JVM
• MicroPython — Python for microcontrollers and embedded systems
• Nuitka — compiler that packages user code with CPython into a static binary
• PyPy — JIT-compiled Python interpreter for speed
• PythonAnywhere — freemium hosted Python installation that runs in the browser
• Stackless Python — Python with lightweight concurrency features
