Python is an interpreted, object–oriented, high level, programming language with dynamic semantics. Developed by Gudio Van Rossum in 1991. It supports multiple programming paradigms, including structured, object-oriented and functional programming. Before diving deep into the topic let’s first brush up the basic concepts related to the question provided to us. A dictionary is a group of items that are unique, changing, and ordered. Curly brackets are used in dictionary writing, and they contain keys and values: The key name can be used to refer to dictionary objects. Data values are kept as key:value pairs in dictionaries. Ordered and unordered ... Read More

Dictionaries are known as the collection data types. They store data in the form of key value pair. They are ordered and changeable i.e., they follow a particular sequence and are indexed. We can change the values for a key and therefore it is manipulative or changeable. Dictionaries does not support duplication of data. Each key can have multiple values associated with it but a single value cannot have more than one key. We can use dictionaries to perform numerous operations. The entire mechanism depends upon the stored values. In this article, we will discuss the techniques that can be ... Read More

Dictionaries are used to store data values in key:value pairs like maps (which unlike other data types holds only a single value as an element). key:value is provided in dictionaries to make it more effective. Keys are unique. Dictionary key must be unique. So, no duplicate values are allowed in dictionaries. Dictionaries items are ordered, changeable, immutable. Changeable means here is that, we can add or remove items after the dictionaries are created. In this article, we will know about how to find a largest element in a dictionary by using different functions. There are many functions to find ... Read More

High-level, all-purpose Python is a very well-liked programming language. Python is utilised for cutting-edge software development projects like web development and machine learning applications. In this article, we will be learning various methods for adding elements to a dictionary. What do You Understand From Dictionary in Python? A dictionary in Python stores a key: value pair, unlike other Data Types that only contain a single value as an element. It is used to store data values like a map. The dictionary includes key-value pairs to help it become more efficient. In a dictionary, each key-value pair is separated ... Read More

In Swift, you can use the weak keyword to declare an array of weak objects. In this article, we will use the weak keyword to store the weak objects or references in an array. Weak References Weak references are one of the solutions to the retain cycle problem in Swift. Note that a weak reference does not increment or decrement the reference count of an object. They can be deallocated even if ARC has a reference count greater than 1. Basically, we use the weak keyword in Swift to mark a reference as weak. Also, a weak reference cannot be ... Read More

Keys are unique. Dictionary key must be unique. So, no duplicate values are allowed in dictionaries. Dictionaries items are ordered, changeable, immutable. Changeable means here is that, we can add or remove items after the dictionaries are created. In python, dictionaries are defined as object with the data type ‘dict’. The values in dictionaries items can be of any data type like string, integer, Boolean ... Read More

In python, multiple items can be kept in a single variable by using lists. One of the four built-in data types in Python for storing data collections is the list; the other three are the tuple, set, and dictionary, each of which has a unique purpose. What is List? Square brackets are used to build lists. The most effective tool in Python is the list because they don't necessarily have to be homogeneous. Data-Types like Integers, Strings, and Objects can all be found in one list. Because lists are mutable, changes can be made to them even after they ... Read More

Lists can be used in Python to maintain several items in a single variable. The list is one of Python's four built-in data types for storing data collections. The other three, tuple, set, and dictionary, each serve a different function. Lists are constructed using square brackets. Because lists don't have to be homogeneous, they are the most useful tool in Python. One list contains Data-Types like Strings, Objects, and Integers. Lists can be modified after they have been generated because they are mutable. The focus of this article is on shorthand and many quick ways to say this in ... Read More

In Swift, there are some directives to perform some checks at compilation time. Based on that, you can perform initial checks to write better code. In this article, we will see how to use the "#warning" directive with some examples. You can use the #warning directive to issue a warning message at compile-time. This is similar to the #warning directive in C and Objective-C. #warning in Swift In Swift, #warning is a compiler directive that allows you to issue a warning message during compilation. This can be useful for reminding yourself or other developers about areas of the code that ... Read More
