History and Evolution of Python

  • 5 min
  • Beginner

Python is one of the most popular and versatile programming languages in the world, known for its simplicity, readability, and wide applicability in different domains.

However, although its popularization and rise is relatively recent, as a programming language it is one of the longest-running among us.

We couldn’t do a course without talking a bit about the history and evolution of Python, from its beginnings to its current state, to understand the impact and development of this influential language.

Origins of Python

Creation by Guido van Rossum (1980s-1990s)

Python was created by Guido van Rossum in the late 1980s in the Netherlands. Van Rossum began working on Python as a side project while at the Centrum Wiskunde & Informatica (CWI) - the National Research Institute for Mathematics and Computer Science. Python was conceived as a successor to the ABC programming language, which Van Rossum had worked on previously.

The first version of Python, known as Python 0.9.0, was released in February 1991. This version included many features that are still present in the language today, such as:

  • Clear and readable syntax.
  • Built-in data types like lists, dictionaries, and strings.
  • Exception handling.
  • Functions and modules.

Python 0.9.0 was a crucial starting point, as it established many of the foundations of the language as we know it today.

Version Evolution

Python 1.x (1994-2000)

Python 1.0 was released in January 1994. This version consolidated many of the features found in version 0.9.0 and introduced new functionalities, including:

  • List comprehensions.
  • Support for extension modules.

During the 1990s, Python grew in popularity, driven by its simplicity and flexibility. At this stage, Python became an attractive option for teaching programming and prototyping.

Python 2.x (2000-2010)

Python 2.0, released in October 2000, marked the beginning of a new era for the language. This version brought significant improvements and new features, including:

  • Garbage collection: An automatic memory management system.
  • List comprehensions: For concise list creation.
  • The unittest module: Introduction of a standard unit testing framework.

Python 2.x continued to evolve with new versions throughout the decade, including Python 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, and 2.7. This last version, Python 2.7, was released in July 2010 and was the last of the 2.x series, with extended support until 2020.

Python 3.x (2008-Present)

Python 3.0, released in December 2008, represented a significant break from previous versions. Although the transition from Python 2 to Python 3 was not fully backward compatible, it introduced many improvements and new features that laid the groundwork for the future of the language. Some of the key features of Python 3.x include:

  • Print as a function: print() becomes a function, eliminating the need for parentheses in the print syntax.
  • Integer division: Division between integers now produces a float by default.
  • Unicode by default: Text strings are handled in Unicode by default, facilitating manipulation of text in multiple languages.

Since the release of Python 3.0, there have been a series of important versions,

Python 3.x Versions

Each of these versions has brought improvements and new features, such as:

  • Python 3.5: Introduction of f-strings for string formatting.
  • Python 3.6: New features like f-strings and the introduction of variable annotations.
  • Python 3.7: Improvements in performance and new functionalities like data classes.
  • Python 3.8: Introduction of the walrus operator (:=) for assignment in expressions.
  • Python 3.9: New operators and improvements in handling generic types.
  • Python 3.10: Improvements in pattern matching syntax.
  • Python 3.11: Focused on performance improvements and language optimization.

Python Today

Today, Python is widely used in a wide variety of fields, including web development, data analysis, artificial intelligence, automation, and more.

The Python community has grown significantly, and the language has been adopted by companies worldwide due to its versatility and ease of use.

The Python Software Foundation (PSF), established in 2001, plays a crucial role in managing the language’s development and organizing community events like PyCon.

Python has had a profound impact on the software industry and computer science education. Its simple design and the vast number of available libraries and tools have facilitated the development of complex applications and research in various disciplines.

The future of Python looks promising, with the community actively involved in the language’s evolution and continuous improvement of its capabilities. Upcoming versions will continue to introduce new features and improvements, solidifying Python as one of the most important and widely used programming languages in the industry.
