The leap year problem (also known as the leap year bug or the leap day bug) is a problem for both digital (computer-related) and non-digital documentation and data storage situations which results from errors in the calculation of which years are leap years, or from manipulating dates without regard to the difference between leap years and common years.
Python supports most object oriented programming (OOP) techniques. It allows polymorphism, not only within a class hierarchy but also by duck typing. Any object can be used for any type, and it will work so long as it has the proper methods and attributes. And everything in Python is an object, including classes, functions, numbers and modules.
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. [33] Python is dynamically type-checked and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional ...
iCalendar components and their properties. iCalendar was created in 1998 [3] by the Calendaring and Scheduling Working Group of the Internet Engineering Task Force, chaired by Anik Ganguly of Open Text Corporation, and was authored by Frank Dawson of Lotus Development Corporation and Derik Stenerson of Microsoft Corporation. iCalendar data files are plain text files with the extension.ics or ...
Immutable objects The state of an object cannot be changed after construction. This implies both that only read-only data is shared and that inherent thread safety is attained. Mutable (non-const) operations can then be implemented in such a way that they create new objects instead of modifying the existing ones.
I certainly won’t object if we included a reference to regular patterns for 13-week quarters, noting that this is the approach taken in practice. — Christoph Päper 11:49, 27 March 2010 (UTC) [ reply ]
The syntax of Nim resembles that of Python. [27] Code blocks and nesting statements are identified through use of whitespace, according to the offside-rule.Many keywords are identical to their Python equivalents, which are mostly English keywords, whereas other programming languages usually use punctuation.
package main import "sync" var arrOnce sync. Once var arr [] int // getArr retrieves arr, lazily initializing on first call. Double-checked // locking is implemented with the sync.Once library function. The first // goroutine to win the race to call Do() will initialize the array, while // others will block until Do() has completed.
