Influence On Other Languages
Python's design and philosophy have influenced several programming languages, including:
- Pyrex and its derivative Cython are code translators that are targeted at writing fast C extensions for the CPython interpreter. The language is mostly Python with syntax extensions for C and C++ features. Both languages produce compilable C code as output.
- Boo uses indentation, a similar syntax, and a similar object model. However, Boo uses static typing and is closely integrated with the .NET Framework.
- Cobra uses indentation and a similar syntax. Cobra's "Acknowledgements" document lists Python first among languages that influenced it. However, Cobra directly supports design-by-contract, unit tests and optional static typing.
- ECMAScript borrowed iterators, generators, and list comprehensions from Python.
- Go is described as incorporating the "development speed of working in a dynamic language like Python".
- Groovy was motivated by the desire to bring the Python design philosophy to Java.
- Karel the Robot is a popular educational programming language created in 1981 at the Stanford University by R.E. Pattis. The original syntax was close to Pascal, but a new edition in NCLab has a syntax very similar to Python.
- OCaml has an optional syntax, called twt (The Whitespace Thing), inspired by Python and Haskell.
- Ruby's creator, Yukihiro Matsumoto, has said: "I wanted a scripting language that was more powerful than Perl, and more object-oriented than Python. That's why I decided to design my own language."
- Alore, a new language with optional typing with Python syntax. (Development in hiatus)
- Mypy (in development), derived from Alore, but mypy will be mostly compatible with Python to make it easier to adopt.
Python's development practices have also been emulated by other languages. The practice of requiring a document describing the rationale for, and issues surrounding, a change to the language (in Python's case, a PEP) is also used in Tcl and Erlang because of Python's influence.

Famous quotes containing the words influence on, influence and/or languages:
“The improvements of ages have had but little influence on the essential laws of man’s existence: as our skeletons, probably, are not to be distinguished from those of our ancestors.”
—Henry David Thoreau (1817–1862)
“My administration is pledged to follow the policies of Mr. Roosevelt in this regard, and while that pledge does not involve me in any obligation to carry them out unless I have Congressional authority to do so, it does require that I take every step and exert every legislative influence upon Congress to enact the legislation which shall best subserve the purposes indicated.”
—William Howard Taft (1857–1930)
“People in places many of us never heard of, whose names we can’t pronounce or even spell, are speaking up for themselves. They speak in languages we once classified as “exotic” but whose mastery is now essential for our diplomats and businessmen. But what they say is very much the same the world over. They want a decent standard of living. They want human dignity and a voice in their own futures. They want their children to grow up strong and healthy and free.”
—Hubert H. Humphrey (1911–1978)
