Python 3.0 broke backward compatibility, and much Python 2 code does not run unmodified on Python 3. [34] Python's dynamic typing combined with the plans to change the semantics of certain methods of dictionaries, for example, made perfect mechanical translation from Python 2.x to Python 3.0 very difficult. A tool called "2to3" does the parts ...
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 ...

Standards. ECMAScript ( / ˈɛkməskrɪpt /; ES) [ 1] is a standard for scripting languages, including JavaScript, JScript, and ActionScript. It is best known as a JavaScript standard intended to ensure the interoperability of web pages across different web browsers. [ 2] It is standardized by Ecma International in the document ECMA-262 .
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.
