Day 6: Creating a Calculator in Python W elcome to Day 6 of our "Master Python in 100 Days" series! Today, we are going to build a simple calculator using Python . This exercise will teach you how to work with basic mathematical operators in Python while also giving you a chance to write your own code from scratch. What Are Operators in Python? Before we jump into the code, let’s talk about operators in Python. Operators are special symbols used to perform operations on variables and values. You’ve already seen them in mathematics. In Python, we have the same kind of operators that we use to add, subtract, multiply, and divide numbers. Let me explain these operators in a simple way: Addition (+) : Adds two numbers. Example: 5 + 3 = 8 Subtraction (-) : Subtracts one number from another. Example: 10 - 4 = 6 Multiplication (*) : Multiplies two numbers. Example: 6 * 7 = 42 Division (/)...
Day 5: Data Types, Variables, and Type Conversion in Python W elcome to Day 5 of our "Master Python in 100 Days" journey! Today, we will explore some of the most important building blocks in Python: data types , variables , and type conversion . Understanding these concepts is essential as they form the basis of how we store and manipulate data in our programs. What are Data Types? Data types tell Python what kind of data we are working with. Python has several built-in data types, and the most common ones are: 1. Integers (int) : These are whole numbers without decimal points, like 10 , -5 , 0 , etc . 2. Floats (float) : These are numbers with decimals, like 3.14 , 0.001 , -2.5 . 3. Strings (str) : A string is a collection of characters (letters, numbers, symbols) enclosed in quotes ( " " or ' ' ) . These are used to represent text. 4. Booleans (bool) : These are either True or False values. It’s used for logical conditions. Chec...
