It draws primarily on features from Perl, Smalltalk, Python, Lisp, Dylan, and CLU.
the complexity introduced by a solution to a design problem must be somehow proportional to the problem's importance. …… Mathematicians don't mind these -- a proof is a proof is a proof, no matter whether it contains 2 or 2000 steps, or requires an infinite-dimensional space to prove something about integers. …… Features of a programming language, whether syntactic or semantic, are all part of the language's user interface. And a user interface can handle only so much complexity or it becomes unusable. This is also the reason why Python will never have continuations, and even why I'm uninterested in optimizing tail recursion.
Once tail recursion elimination exists, developers will start writing code that depends on it, and their code won't run on implementations that don't provide it …… I don't believe in recursion as the basis of all programming. This is a fundamental belief of certain computer scientists, especially those who love Scheme and like to teach programming by starting with a "cons" cell and recursion.

Python is a simple, yet powerful, interpreted programming language that bridges the gap between C and shell programming, and is thus ideally suited for "throw-away programming" and rapid prototyping. Its syntax is put together from constructs borrowed from a variety of other languages; most prominent are influences from ABC, C, Modula-3 and Icon.
The Python interpreter is easily extended with new functions and data types implemented in C. Python is also suitable as an extension language for highly customizable C applications such as editors or window managers.
Python is an interpreted object oriented programming language. This document describes how to write modules in C or C++ to extend the Python interpreter with new modules. Those modules can define new functions but also new object types and their methods. The document also describes how to embed the Python interpreter in another application, for use as an extension language. Finally, it shows how to compile and link extension modules so that they can be loaded dynamically (at run time) into the interpreter, if the underlying operating system supports this feature.
The modulo operator always yields a result with the same sign as its second operand (or zero); …… The integer division and modulo operators are connected by the following identity: x == (x/y)*y + (x%y).CoffeeScript is a programming language whose syntax is clearly designed to match much of Python (with additional inspirations from Perl, ECMAScript, Ruby, etc.).
Pyston was started at Dropbox in 2014 ……. …… In 2017 …… Pyston project was shut down. …… In 2019 the Pyston developers regrouped ……. …… In mid-2021 the Pyston developers joined Anaconda …….
Nim's syntax is strongly reminiscent of Python's, as it uses indented code blocks and some of the same syntax (such as the way if/elif/then/else blocks are constructed).
After more than a decade of steady growth, Python's adoption has accelerated significantly.
The default installed Python version shall be 2.4.2 or greater.
String slicing came from Algol-68 and Icon.
Of course, it also greatly benefited from the experiences hard-won by many other languages in the field, drawing ideas from Objective-C, Rust, Haskell, Ruby, Python, C#, CLU, and far too many others to list.
Python can be seen as a dialect of Lisp with "traditional" syntax (what Lisp people call "infix" or "m-lisp" syntax).
The term broadcasting describes how NumPy treats arrays with different shapes during arithmetic operations. Subject to certain constraints, the smaller array is “broadcast” across the larger array so that they have compatible shapes.
even though the design of C is far from ideal, its influence on Python is considerable.
DataFrame is a 2-dimensional labeled data structure with columns of potentially different types. You can think of it like a spreadsheet or SQL table, or a dict of Series objects. It is generally the most commonly used pandas object.
aspectlib is an aspect-oriented programming, monkey-patch and decorators library. It is useful when changing behavior in existing code is desired. It includes tools for debugging and testing: simple mock/record and a complete capture/replay framework.

Compared with other programming languages, Python’s class mechanism adds classes with a minimum of new syntax and semantics. It is a mixture of the class mechanisms found in C++ and Modula-3.
This module provides regular expression matching operations similar to those found in Perl.
simple_stmts:
| simple_stmt !';' NEWLINE # Not needed, there for speedup
| ';'.simple_stmt+ [';'] NEWLINE
statements: statement+statement: compound_stmt | simple_stmts
……block:
| NEWLINE INDENT statements DEDENT
| simple_stmts
almost all platforms map Python floats to IEEE-754 “double precision”.
The C3 method itself has nothing to do with Python, since it was invented by people working on Dylan and it is described in a paper intended for lispers.
python library for design by contract (DbC) and checking values, exceptions, and side-effects.
replace "CLU" with "Python", "record" with "instance", and "procedure" with "function or method", and you get a pretty accurate description of Python's object model.
Lambda expressions are particularly useful in combination with map(), filter() and reduce(), described below. Thanks to Amrit Prem for submitting this code (as well as map(), filter(), reduce() and xrange())!
The relational operators group left-to-right, but this fact is not useful;a<b<cis parsed as(a<b)<c, and evaluates to either0or1.
