The programming language Python was conceived in the late 1980s, [ 1] and its implementation was started in December 1989 [ 2] by Guido van Rossum at CWI in the Netherlands as a successor to ABC capable of exception handling and interfacing with the Amoeba operating system. [ 3] Van Rossum is Python's principal author, and his continuing ...
Python is a multi-paradigm programming language. Object-oriented programming and structured programming are fully supported, and many of their features support functional programming and aspect-oriented programming (including metaprogramming [ 70] and metaobjects ). [ 71] Many other paradigms are supported via extensions, including design by ...

Python syntax and semantics. A snippet of Python code with keywords highlighted in bold yellow font. The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers). The Python language has many similarities to Perl, C, and Java ...
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.
Like natural languages, programming languages follow rules for syntax and semantics. There are thousands of programming languages [1] and new ones are created every year. Few languages ever become sufficiently popular that they are used by more than a few people, but professional programmers may use dozens of languages in a career.
An early Netscape employee, Brendan Eich, created the JavaScript programming language, the most widely used language for client-side scripting of web pages. A founding engineer of Netscape, Lou Montulli, created HTTP cookies. The company also developed SSL which was used for securing online communications before its successor TLS took over.
The first functioning programming languages designed to communicate instructions to a computer were written in the early 1950s. John Mauchly 's Short Code, proposed in 1949, was one of the first high-level languages ever developed for an electronic computer. [ 8] Unlike machine code, Short Code statements represented mathematical expressions in ...
