✅Python Control Flow Part 1: if, elif, else🧠💻 What is Control Flow? 👉 Your code makes decisions 👉 Runs only when conditions are met • Each condition is True or False • Python checks from top to bottom 🔹Basic if statement age = 20 if age >= 18: print("You are eligible to vote") ▶️ Checks if age is 18 or more. Prints "You are eligible to vote" 🔹if-else example age = 16 if age >= 18: print("Eligible to vote") else: print("Not eligible") ▶️ Age is 16, so it prints "Not eligible" 🔹elif for multiple conditions marks = 72 if marks >= 90: print("Grade A") elif marks >= 75: print("Grade B") elif marks >= 60: print("Grade C") else: print("Fail") ▶️ Marks = 72, so it matches >= 60 and prints "Grade C" 🔹Comparison Operators a = 10 b = 20 if a != b: print("Values are different") ▶️ Since 10 ≠ 20, it prints "Values are different" 🔹Logical Operators age = 25 has_id = True if age >= 18 and has_id: print("Entry allowed") ▶️ Both conditions are True → prints "Entry allowed" ⚠️Common Mistakes: • Using = instead of == • Bad indentation • Comparing incompatible data types 📌Mini Project – Age Category Checker age = int(input("Enter age: ")) if age < 13: print("Child") elif age <= 19: print("Teen") else: print("Adult") ▶️ Takes age as input and prints the category 📝Practice Tasks: 1. Check if a number is even or odd 2. Check if number is +ve, -ve, or 0 3. Print the larger of two numbers 4. Check if a year is leap year ✅Practice Task Solutions – Try it yourself first👇 1️⃣ Check if a number is even or odd num = int(input("Enter a number: ")) if num % 2 == 0: print("Even number") else: print("Odd number") ▶️% gives remainder. If remainder is 0, it's even. 2️⃣ Check if number is positive, negative, or zero num = float(input("Enter a number: ")) if num > 0: print("Positive number") elif num < 0: print("Negative number") else: print("Zero") ▶️ Uses > and < to check sign of number. 3️⃣ Print the larger of two numbers a = int(input("Enter first number: ")) b = int(input("Enter second number: ")) if a > b: print("Larger number is:", a) elif b > a: print("Larger number is:", b) else: print("Both are equal") ▶️ Compares a and b and prints the larger one. 4️⃣ Check if a year is leap year year = int(input("Enter a year: ")) if (year % 4 == 0 and year % 100 != 0) or (year % 400 == 0): print("Leap year") else: print("Not a leap year") ▶️ Follows leap year rules: - Divisible by 4 ✅ - But not divisible by 100 ❌ - Unless also divisible by 400 ✅ 📅Daily Rule: ✅ Code 60 mins ✅ Run every example ✅ Change inputs and observe output 💬Tap ❤️ if this helped you!
