In this lecture, we build a simple calculator in Python using if-elif-else statements. This session is designed for beginners to help them understand conditional statements through a practical example. You will learn how to take user input and perform basic arithmetic operations such as addition, subtraction, multiplication, and division using Python. This is Lecture 16 of the Python programming series and focuses on writing clean, easy-to-understand code. Don’t forget to like, share, and subscribe for more Python tutorials and programming lessons.
