 <h1>Decoding secret messages with methods</h1>
 <p>In this exercise, we’ll practice string manipulation and slicing. You’ll work with a secret message encoded using various string operations and learn how to apply some new methods like <code>title()</code>, <code>replace()</code> and <code>count()</code>. By following a series of steps, you’ll gradually decode the message. Let’s begin with the encoded message and work through each decoding step:</p>

 <h1>Classifying temperatures</h1>
 <p>In this exercise, we’ll practice using conditional statements to classify temperatures into different categories. We’ll create a program that takes a temperature input from the user and provides a classification based on the temperature range. This exercise will help you understand how to use if-elif-else statements, handle user input, and implement a simple loop for program repetition.</p>

 <h1>Number guessing game</h1>
 <p>In this exercise, we’ll create an interactive number guessing game for two players. This game will help you practice using loops, conditional statements, and user input handling. You’ll also learn how to implement a simple game logic and manage player turns. This exercise will reinforce your understanding of control structures and basic development concepts in Python.</p>
