Python 2.6 was released to coincide with Python 3.0, and included some features from that release, as well as a "warnings" mode that highlighted the use of features that were removed in Python 3.0. [ 28 ] [ 10 ] Similarly, Python 2.7 coincided with and included features from Python 3.1, [ 29 ] which was released on June 26, 2009.
Guido van Rossum began working on Python in the late 1980s as a successor to the ABC programming language and first released it in 1991 as Python 0.9.0. [36] Python 2.0 was released in 2000. Python 3.0, released in 2008, was a major revision not completely backward-compatible with earlier versions.

In some languages, particularly scripting languages, the "Hello, World!" program can be written as one statement, while in others (more so many low-level languages) many more statements can be required. For example, in Python, to print the string Hello, World! followed by a newline, one only needs to write print ("Hello, World!").
The functional languages community moved to standardize ML and Lisp. Research in Miranda, a functional language with lazy evaluation, began to take hold in this decade. One important new trend in language design was an increased focus on programming for large-scale systems through the use of modules, or large-scale organizational units of code.
He is the creator of the Python programming language, for which he was the "benevolent dictator for life" (BDFL) until he stepped down from the position on 12 July 2018. [ 4 ] [ 5 ] He remained a member of the Python Steering Council through 2019, and withdrew from nominations for the 2020 election.
The vast majority of programming languages in use today have a free software implementation available. Since the 1990s, the release of major new programming languages in the form of open-source compilers and/or interpreters has been the norm, rather than the exception. Examples include Python in 1991, Ruby in 1995, and Scala in 2003.
