Convert Image to String and vice-versa in Python
When we speak of "converting an image into string format and back again in Python", this refers to converting image files to something that can be stored and managed using strings of characters, before eventually returning it back into its original image format. Converting Image to String − Converting images to strings involves transcribing their binary data into text format for transmittal or storage over network protocols that require text-based images. This conversion method can help us transmit or store an image more efficiently when working with APIs, databases or sending images over network protocols requiring text data transmission or ...
Read MoreHow to Create Custom Turtle shapes in Python?
Python’s Turtle library is used for generating 2D graphics and animations. It has a very simple interface with help of which we can create shapes and patterns on the screen. It comes with some built-in shapes like squares, circles, triangles etc. However, we can even create our own shapes with the help of Turtle. In this article, we are going to see how to create custom turtle shapes in python. Before going forward with the creating custom shapes we need to install Turtle on the system and this can be done by simply using the following command − pip install ...
Read MoreHow to Create Bottom Navigation using Kivymd and Python?
KivyMD is a commonly known library of Python which offers us with a collection of Material Design (MD) compliant widgets. These widgets can be used along with the kivy framework which is another library and is used for creating multi-touch applications. The large number of UI elements that kivyMD provides us with, include buttons, cards, dialogs, menus and many more such elements, all of which are designed to give an appealing look and feel.

Read MoreJava Program to Encode a Message Using Playfair Cipher
Encrypting is the task of transforming information into an unreadable format or cipher text. It is usually done to protect the confidentiality of information. There are many ways and algorithms to encrypt data. One such example is the Playfair cipher algorithm. In this article, we are going to see how to write a Java program to encode a message using Playfair cipher. Playfair cipher makes use of a 5X5 grid or matrix and a set of pre-defined rules. To encrypt, we require a key and the plain text to be encrypted. Steps Now let us see the steps to encrypt ...
Read MoreInsert a character after every n characters in JavaScript
Insertion of a specific character after every n characters in Javascript is an easy to understand concept and gives us a better understanding about Javascript's functions. Here n can be any whole number ranging from 1 to less than the length of the string. In this article we will deal with a variable inputString = "abcdefghijklmnopqrstuvwxyz, " and aim to append a "-" character after every 5 characters. There are several ways to accomplish this with JavaScript, which are as follows − Making use of the slice() method In JavaScript, the slice() function is used to extract a portion of ...
