In what year was Python first released?

In what year was Python first released? Python was first released in 1991. Guido van Rossum published the early language after beginning its implementation in December 1989 at CWI in the Netherlands.

The first public release is commonly identified as Python 0.9.0 in 1991; historical accounts also describe the code published to the alt.sources newsgroup in February 1991 as Python 0.9.1. This early version already included major features such as classes with inheritance, exception handling, functions, and built-in data types including lists, dictionaries, and strings.

Python’s development continued through the 1990s, with Python 1.0 arriving in 1994 and Python 2.0 in 2000. Python 3.0, released in 2008, was a major revision that introduced backward-incompatible changes. Thus, 1991 refers to Python’s first public release, not the later releases that established the versions many programmers remember.

The language was conceived in the late 1980s as a successor to ABC and was influenced by the need for a readable, extensible scripting language.
