How do I make a subclass from a super class in Python?
In this article we are going to discuss how to create subclass from a super class in Python. Before proceeding further let us understand what is a class and a super class. A class is a user-defined template or prototype from which objects are made. Classes offer a way to bundle together functionality and data. The ability to create new instances of an object type is made possible by the production of a new class. Each instance of a class may have attributes connected to it to preserve its state. Class instances may also contain methods for changing their state ...
Read MoreExplain Python class method chaining
In OOP languages methods are a piece of code that can perform a specific task to produce a desired output. Methods are created inside classes and are invoked or called by objects of the class. Methods are extremely useful in programming as they provide modularity to code by breaking a complex code into manageable blocks. Methods can function independently of other methods, thus making it easy to check individual functionality within a program. Method chaining in Python Methods chaining is a style of programming in which invoking multiple method calls occurs sequentially. It removes the pain of assigning variables at ...
Read MorePython program to split and join a string?
We'll learn how to split and join a string in Python in this article. Python defines strings as a collection of characters enclosed in one, two, or three quotations. When a string is split, it is divided into smaller strings using a specific delimiter. A set of one or more characters used to define a boundary is known as a delimiter. Anything could serve as a delimiter. The comma (, ), semicolon (;), tab (t), space (), and pipe (|) are the most widely used delimiters. Everywhere the specified delimiter appears in a given string, we must split it, and ...
Read MorePython Program to replace a word with asterisks in a sentence
The use of the symbol * (asterisks) in writing or printing as a reference mark, a sign that some letters or words have been omitted, a way to indicate a possible but unproven linguistic form, or for other arbitrary purposes. In this article we will discuss different ways to replace a word with asterisks in a sentence in Python. Input-Output Scenarios Following is an input and its output scenario of replacing a word in a sentence with asterisks − Input: Welcome to the TutorialsPoint family. Output: Welcome to the TutorialsPoint ****** We can see in the above scenario that ...
Read MorePython program to Remove and print every third from list until it becomes empty?
In this article, we will learn how to remove and print every third element or item from the list until it becomes empty using Python Program. First we create a list, the index of the starting address is 0 and the position of the first third element is 2 and need to traverse till the list becomes empty and another important work to do every time we have to find the index of the next third element and print the value and after that reduce the length of the list. Input-Output Scenario Following is the input and its output scenario ...
Read MorePython program to multiply all numbers in the list?
You will understand how to multiply every number in a list in Python in this article using various methods. A list is an ordered collection of values that are enclosed in square brackets. List contains values known as items that can be retrieved by their unique index. We'll create a function that multiplies each value in the list and outputs the result. The result of multiplying all the values is a single thing. For instance, the result will be 36 for the list [3, 2, 6]. We will go over the various methods for calculating the sum of all the ...
Read MoreHow to return a JSON object from a Python function in Tkinter?
JavaScript Object Notation, or JSON is a simple data format that is used to exchange data between many different languages. It is simple to read for people and simple for computers to parse. Python reads JSON text as a quoted-string that contains the value in each key-value mapping. Once parsed, it is accessible in Python as a dictionary object. JSON data can be encoded and decoded using the built-in package json in Python. You must first import the json library in order to work with files of the json type. Purposeco JSON Python to JSON conversion is done using serialization. ...
Read MorePython program to sort a tuple by its float element
This article will demonstrate how write a Python program to sort a tuple (made up of float elements) using its float elements. Here, we'll look at both how to sort using the in-built sorted() function and how to sort using the in-place method of sorting. Input-Output Scenarios Following is an input and its output scenario determining the sorting of a tuple by its float element − Scenario-1 Input: tuple = [(‘Dengu’, ’54.865’), (‘Malaria’, ‘345.743’), (‘Corona’, ‘456.864’), (‘Typhoid’, ‘35.285’), (‘Jaundice’, ’83.367’)] Output: [(‘Corona’, ‘456.864’), (‘Malaria’, ‘345.743’), (‘Jaundice’, ’83.367’), (‘Dengu’, ’54.865’), (‘Typhoid’, ‘35.285’)] In the above scenario we can see that ...
Read MorePython Program to find mirror characters in a string
This article teaches you how to write a python program to find mirror characters in a string. Let us first understand what mirror characters in a string are. Two identical alphabetically positioned characters, one from the front and the other from the back, are known as mirror characters. For example, the alphabet a's mirror character is "z, " "b's" is "y, " and so on. Input-Output Scenario Following is an input and its output example of mirror characters in a string − Input: p = 3 Input string = Coding Output: Cowrmt Here, the alphabets “d”, “i”, “n”, “g” ...
Read MorePython Program to check if two given matrices are identical
Matrix refers to a collection of numbers arranged in rows and columns to form a rectangular array. The numbers make up the matrix's entries, or elements. We need to create a Python function to determine whether two given matrices are identical. In other words, we say that two matrices are identical if all of the elements in their respective places are the same. Identical Matrices Two matrices are only considered equal if and when they meet the requirements listed below − There should be an equal number of rows and columns in each matrices. The identical corresponding items should ...
