Finding the roots of polynomials is an essential operation in mathematics, and NumPy provides an easy and efficient way to accomplish this task. NumPy is a powerful library for scientific computing in Python, and its functions for polynomial manipulation are especially useful. Syntax The NumPy library has a function named roots() that can be used to find the roots of a polynomial. numpy.roots(p) where p is the polynomial coefficients represented as a 1D array or sequence. The function returns an array of the roots of the polynomial. Algorithm With NumPy, finding a polynomial's roots is a rather straightforward process ... Read More

Profit and loss percent is an important financial metric that helps in analyzing the profitability of a business. It is calculated by finding the difference between the total revenue and total cost, and then dividing that value by the total cost. In this technical blog, we will learn how to find the profit and loss percent in a given Excel sheet using Pandas. We will be using the same Excel sheet that we used in our previous blog post on finding profit and loss. Algorithm Import the Pandas library and read the Excel sheet using the read_excel() function. Apply ... Read More

Python, a generally adaptable and effective programming language, has picked up significant popularity over a long time. The item-oriented nature of Python lets within the execution of a few high-quality capacities, such as inheritance and polymorphism. In this post, we will delve into two lesser-recognized, yet charming techniques that allow for custom-designed inheritance checks in Python: subclasscheck and subclasshook. What are Subclasscheck and Subclasshook? In Python, it is not unusual to determine if a class is a subclass of some other class by utilizing the built-in issubclass() function. By default, this function checks the inheritance tree to decide the connection ... Read More

Python, a versatile and broadly used programming language, is thought for its simplicity and widespread feature set.
