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...

Day 4 :  Comments, Escape Sequences & Print Statement W elcome back to Day 4 of our Python journey! Today, we will dive deeper into three important topics: comments , escape sequences , and the print statement . Understanding these concepts is essential for writing clear and effective code. Let’s explore them in detail! What are Comments? Definition : Comments are notes that you write in your code. They help explain what the code does. Python ignores these comments, so they don't affect how your program runs. Comments are helpful for anyone who reads your code, including you! Comments are very useful for: Explaining complex logic Making the code easier to read Providing context for future reference Types of Comments 1.  Single-Line Comments : These comments are written on one line and start with the # symbol. Python will ignore everything after the # on that line. Example: In this example, # This is a single-line comment explains that the line below it prints "Hello,...

Day 3: Writing Our First Python Program in Detail  W elcome back to Master Python in 100 Days ! Today, on Day 3, we are going to write our very first Python program from scratch, step-by-step. This isn’t just about writing code; it’s about understanding every line and making sure we know exactly what’s happening in our program. Let's get started! A Quick Review: What We Did on Day 1 If you remember, on the very first day of the   Master Python in 100 Days , we touched upon how to use the print() function to display basic output on the screen. That was a warm-up , where we gave a quick look at the print() function. But starting from today, we will dive deeper into the actual use of print() . By the end of this session, you’ll not only understand how to use print() properly, but also learn how to avoid common errors and use it in your own Python scripts. So, let’s take our Python learning journey one step further!   Introduction to the print() Function : The ...

Day 2: Understanding Modules and Pip in Python W elcome to Day 2 of our Python learning journey! Today, we will dive deeper into the concepts of modules and the package manager pip. What Are Modules? Modules in Python are like libraries filled with reusable code. They save you time by allowing you to use existing functionality instead of writing everything from scratch. Think of them as tools in a toolbox—each serves a specific purpose. Types of Modules: 1.  Built-in Modules : These come with Python and require no installation. Examples include:       1.  math : For mathematical functions (e.g., math.sqrt() for square roots).       2.  datetime : For handling dates and times (e.g., datetime.datetime.now() to get the current date and time).       3.  random : For generating random numbers. 2.   External Modules : These are created by third-party developers and need to be installed via pip. Popular examples include...

Day 1: Introduction to Python Hello everyone! Welcome to Day 1 of our 100 Days to Learn Python journey! Today, we will start by understanding what Python is, its importance, and how to get started. What is Python? Python is a popular, high-level programming language that was created by Guido van Rossum and first released in 1991 . It’s designed to be easy to read and simple to write, making it perfect for both beginners and advanced programmers. Python allows developers to focus on solving problems rather than worrying about the complex syntax often found in other programming languages. Why Learn Python? 1. High demand: Many companies need Python programmers. 2. Versatile: You can use Python for web development, data analysis, machine learning, game   development, automation, and more. 3.  Great community: There are many resources, forums, and libraries available online.    Key Features of Python: 1. Simple and Easy to Learn : Python’s syntax is similar to the...
