Python and PyQt are powerful tools for developing desktop applications. In this tutorial, we will explore how to leverage these technologies to create interactive and user−friendly desktop applications. Python is a versatile and easy−to−learn programming language, while PyQt is a Python binding for the Qt framework, which provides a rich set of libraries and tools for building graphical user interfaces (GUIs). In this tutorial, we will guide you through the process of building a desktop application using Python and PyQt. In this tutorial, we will cover the following steps to develop a desktop application: Setting up the Development Environment First, ... Read More
C compiler treats a string as an array of characters, so it is easy to remove characters of a string based on their position. The first and last position of the string have to be checked for the presence of parenthesis and have to be removed. The string can be copied into another variable and presented. There are many predefined functions in C that can be used effectively to manipulate strings. Removing a character from the starting or ending position is easily achieved in C with the help of the functions. Removing starting and ending paranthesis from string ... Read More
The title "Count of primes after converting given binary number in base between L and R" refers to a math problem that involves converting a binary number into a base between L and R and then counting the number of prime numbers that come from the conversion. In math, a prime number is a whole number that is greater than 1 and can only be divided by 1 and itself. To turn a binary number into a number with a different base, the number has to be written in a different number system. The number system's base is the number ... Read More
The government issues a unique identification number known as a GST number to businesses and individuals who have registered for GST. As part of the validation procedure, the GST number is checked for correctness and legitimacy. The format of the number is frequently checked during the verification process to make sure it is correct and conforms to the format needed by the tax authorities of the relevant country. In order to confirm the validity of the number and that it belongs to the person seeking it, the verification phase may also involve cross-referencing it with the database of the tax ... Read More

Python and Selenium are two widely recognized and influential tools for web automation tasks, including testing, web scraping, and web interaction. Among the various tasks that web automation can perform, clicking a button on a webpage is one of the most common actions. The process of clicking a button on a webpage involves locating the button element using its text label. In this article, we offer a comprehensive guide on how to automate the process of clicking a button on a webpage using Python and Selenium by identifying the button element through its text label. We will take you ... Read More
Millions of people and organisations use Excel, a robust spreadsheet programme, to organise and analyse data. The capacity of Excel to execute calculations using formulae is one of the primary characteristics that contribute to its versatility. Excel formulas let you work with data, conduct a variety of mathematical operations, and establish dynamic relationships between cells. Understanding the precise cell references used in a formula becomes crucial when working with complex formulas or vast datasets. You can better understand how data is used and referred to in computations by removing cell references from formulas. You may more effectively manage dependencies, ... Read More
CSS viewer extension is a chrome extension which acts as a property viewer and was made by Nicolas Huon. The user has to click on the toolbar icon and then he can hover his cursor on any element to view the element’s properties.

In Java, both Integer.parseInt() and Integer.valueOf() methods are used for the conversion of a String into an Integer. These static methods belong to the Integer class of java.lang package and throws a NumberFormatException if the string is not a valid representation of an integer. But wait, the question arise here is that why Java provides two methods with the same functionality. Although they are used to serve similar jobs, there exist a few distinctions between them in terms of syntax and return type. In this article, we are going to explain the difference between Integer.parseInt() and Integer.valueOf() methods with ... Read More
The Integer class of Java provides two constants named Integer.MAX_VALUE and Integer.MIN_VALUE represents the maximum and minimum possible values for an integer variable in Java. The actual value of Integer.MAX_VALUE is 231 -1 which is equivalent to 2147483647 and the actual value of Integer.MIN_VALUE is -231 which is equivalent to -2147483648. For our convenience, instead of writing this big whole number in our program, we use their constant representation. This article aims to explore the utility and how to use Integer.MAX_VALUE and Integer.MIN_VALUE in our Java programs. Examples of Integer.MAX_VALUE and Integer.MIN_VALUE in Java In this section, we ... Read More
