IDLE (short for Integrated Development and Learning Environment) [2] [3] is an integrated development environment for Python, which has been bundled with the default implementation of the language since 1.5.2b1. [4] [5] It is packaged as an optional part of the Python packaging with many Linux distributions.
Adding from __future__ import division causes a module used in Python 2.7 to use Python 3.0 rules for division (see above). In Python terms, / is true division (or simply division), and // is floor division. / before version 3.0 is classic division. [122] Rounding towards negative infinity, though different from most languages, adds consistency.
Edits to the Python 3.x code were discouraged for so long as the code needed to run on Python 2.x. [10] This is no longer recommended; as of 2012 the preferred approach was to create a single code base that can run under both Python 2 and 3 using compatibility modules. [37]
Introduced in Python 2.2 as an optional feature and finalized in version 2.3, generators are Python's mechanism for lazy evaluation of a function that would otherwise return a space-prohibitive or computationally intensive list. This is an example to lazily generate the prime numbers:
CMake is a free, cross-platform, software development tool for building applications via compiler-independent instructions. It also can automate testing , packaging and installation . It runs on a variety of platforms and supports many programming languages .
Modula-3 is a programming language conceived as a successor to an upgraded version of Modula-2 known as Modula-2+.It has been influential in research circles (influencing the designs of languages such as Java, C#, Python [8] and Nim), but it has not been adopted widely in industry.
In most of today's popular programming languages and operating systems, a computer program usually only has a single entry point.. In C, C++, D, Zig, Rust and Kotlin programs this is a function named main; in Java it is a static method named main (although the class must be specified at the invocation time), and in C# it is a static method named Main.
Nim provides string interpolation via the strutils module. Formatted string literals inspired by Python F-string are provided via the strformat module, the strformat macro verifies that the format string is well-formed and well-typed, and then are expanded into Nim source code at compile-time.
