Python was conceived in the late 1980s[42] by Guido van Rossum at Centrum Wiskunde & Informatica (CWI) in the Netherlands; it was conceived as a successor to the ABC programming language, which was inspired by SETL,[43] capable of exception handling and interfacing with the Amoeba operating system.[12] Python implementation began in December 1989.[44] Van Rossum assumed sole responsibility for the project, as the lead developer, until 12 July 2018, when he announced his "permanent vacation" from responsibilities as Python's "benevolent dictator for life" (BDFL); this title was bestowed on him by the Python community to reflect his long-term commitment as the project's chief decision-maker.[45] (He has since come out of retirement and is self-titled "BDFL-emeritus".) In January 2019, active Python core developers elected a five-member Steering Council to lead the project.[46][47]The name Python is said to derive from the British comedy series Monty Python's Flying Circus.[48]
Python 2.0 was released on 16 October 2000, with many major new features such as list comprehensions, cycle-detecting garbage collection, reference counting, and Unicode support.[49] Python 2.7's end-of-life was initially set for 2015, and then postponed to 2020 out of concern that a large body of existing code could not easily be forward-ported to Python 3.[50][51] It no longer receives security patches or updates.[52][53] While Python 2.7 and older versions are officially unsupported, a different unofficial Python implementation, PyPy, continues to support Python 2, i.e., "2.7.18+" (plus 3.10), with the plus signifying (at least some) "backported security updates".[54]
Python 3.0 was released on 3 December 2008, with some new semantics and changed syntax. At least every Python release since (the now unsupported) 3.5 has added some syntax to the language; a few later releases have removed outdated modules and have changed semantics, at least in a minor way.
As of 12 March 2025, Python 3.13 is the latest stable release. This version currently receives full bug-fix and security updates, while Python 3.12—released in October 2023—will have active bug-fix support only until April 2025. Python 3.9[55] is the oldest supported version of Python (albeit in the 'security support' phase), because Python 3.8 has become an end-of-life product.[56][57] Starting with Python 3.13, this and later versions receive two years of full support (which has increased from one and a half years), followed by three years of security support; this is the same total duration of support as previously.
Security updates were expedited in 2021 and again twice in 2022. More issues were fixed in 2023 and in September 2024 (for Python versions 3.8.20 through 3.12.6)—all versions (including 2.7)[58] had been insecure because of issues leading to possible remote code execution[59] and web-cache poisoning.[60]
Python 3.10 added the | union type operator[61] and the match and case keywords (for structural pattern matching statements). Python 3.11 expanded exception handling functionality. Python 3.12 added the new keyword type. Notable changes from version 3.10 to 3.11 include increased program execution speed and improved error reporting.[62] Python 3.11 is claimed to be 10%–60% faster than Python 3.10, and Python 3.12 increases by an additional 5% . Python 3.12 also includes improved error messages (again improved in 3.14) and many other changes.
Python 3.13 introduces more syntax for types; a new and improved interactive interpreter (REPL), featuring multi-line editing and color support; an incremental garbage collector, which results in shorter pauses for collection in programs that have many objects, as well as increasing the improved speed in 3.11 and 3.12); an experimental just-in-time (JIT) compiler (such features, can/needs to be enabled specifically for the increase in speed);[63] and an experimental free-threaded build mode, which disables the global interpreter lock (GIL), allowing threads to run more concurrently, as enabled inpython3.13t or python3.13t.exe.
Python 3.13 introduces some changes in behavior, i.e., new "well-defined semantics", fixing bugs, and removing many deprecated classes, functions and methods (as well as some of the Python/C API and outdated modules). "The old implementation of locals() and frame.f_locals was slow, inconsistent and buggy, and it had many corner cases and oddities. Code that works around those may need revising; code that uses locals() for simple templating or print debugging should continue to work correctly."[64]
Python 3.13 introduces the experimental free-threaded build mode, which disables the Global Interpreter Lock (GIL); the GIL is a feature of CPython that previously prevented multiple threads from executing Python bytecode simultaneously. This optional build, introduced through PEP 703, enables better exploitation of multi-core CPUs. By allowing multiple threads to run Python code in parallel, the free-threaded mode addresses long-standing performance bottlenecks associated with the GIL. This change offers a new path for parallelism in Python, without resorting to multiprocessing or external concurrency frameworks.[65]
Some additional standard-library modules will be removed in Python 3.15 or 3.16, as will be many deprecated classes, functions and methods.[66][67]
Python 3.11 adds Sigstore digital verification signatures for all CPython artifacts (in addition to PGP). Because the use of PGP has been criticized by security practitioners, Python is transitioning to Sigstore exclusively and dropping PGP from 3.14.[68]
Python 3.14 is now in the alpha 3 phase. With regard to possible change to annotations, "In Python 3.14, from __future__ import annotations will continue to work as it did before, converting annotations into strings."[69]
Python Enhancement Proposal (PEP) 711 proposes PyBI—a standard format for distributing Python binaries.[70]
Python 3.15 will "Make UTF-8 mode default";[71] This mode is supported in all current Python versions, but it currently must be opted into. UTF-8 is already used by default on Windows (and other operating systems) for most purposes; an exception is opening files. Enabling UTF-8 also makes code fully cross-platform.
