if age >= 18: print("Eligible") ❌ Incorrect Indentation if age >= 18: print("Eligible") Python requires proper indentation. Correct: if age >= 18: print("Eligible") 🔹 11. Real-World Data Science Example prediction = 0.82 if prediction >= 0.5: print("Spam Email") else: print("Not Spam") Many Machine Learning classification models use similar logic to convert prediction probabilities into categories. 🎯 Practice Questions 1. Check whether a number is positive or negative. 2. Check whether a person is eligible to vote. 3. Create a grading system using "if...elif...else". 4. Check whether a number is even or odd. 5. Determine the largest of three numbers. 🎯 Key Takeaways ✅ Use "if" to execute code when a condition is True. ✅ Use "else" to execute code when the condition is False. ✅ Use "elif" to check multiple conditions. ✅ Nested "if" statements allow more complex decision-making. ✅ Logical operators (and, or, not) help combine conditions. ✅ The ternary operator provides a concise way to write simple "if...else" statements. Conditional statements are the foundation of decision-making in Python and are widely used in automation, data analysis, machine learning, and AI applications. Double Tap ❤️ For Part-5
