The Zen of Python output in a terminal. The Zen of Python is a collection of 19 "guiding principles" for writing computer programs that influence the design of the Python programming language. [1] Python code that aligns with these principles is often referred to as "Pythonic". [2] Software engineer Tim Peters wrote this set of principles and ...
Python's development is conducted largely through the Python Enhancement Proposal (PEP) process, the primary mechanism for proposing major new features, collecting community input on issues, and documenting Python design decisions. [175] Python coding style is covered in PEP 8. [176] Outstanding PEPs are reviewed and commented on by the Python ...
Similar to Python, there is the possibility of extending MicroPython's functionality with custom libraries which extend the ability of the existing libraries and firmware. [20] In MicroPython, files ending with .py take preference over other library aliases which allows users to extend the use and implementation of the existing libraries. [19]
The name read–eval–print loop comes from the names of the Lisp primitive functions which implement this functionality: The read function accepts an expression from the user, and parses it into a data structure in memory. For instance, the user may enter the s-expression (+ 1 2 3), which is parsed into a linked list containing four data ...
Python sets are very much like mathematical sets, and support operations like set intersection and union. Python also features a frozenset class for immutable sets, see Collection types. Dictionaries (class dict) are mutable mappings tying keys and corresponding values. Python has special syntax to create dictionaries ({key: value})
In computer programming, foreach loop (or for-each loop) is a control flow statement for traversing items in a collection. foreach is usually used in place of a standard for loop statement.
Under Unix, the "everything is a file" paradigm naturally leads to a file-based event loop. Reading from and writing to files, inter-process communication, network communication, and device control are all achieved using file I/O, with the target identified by a file descriptor. The select and poll system calls allow a set of file descriptors ...
GYP (Generate Your Projects), a build automation tool (similar to CMake and Premake) designed to generate native IDE project files (e.g., Visual Studio, Xcode, etc.) from a single configuration; Image Packaging System (IPS), an advanced, cross-platform package management system primarily used in Solaris and OpenSolaris/illumos derivatives
