1. Conditional Statements in
Python
Interactive Class Session

2. Real-Life Analogy
• Example:
• "If it's raining, I’ll take an umbrella. Else, I’ll go
without it."
• Conditional logic is used in daily life, and in
programming too!

3. What Are Conditional Statements?
• if: Checks the first condition
• elif: Checks another condition if previous ones
fail
• else: Executes when no above conditions are
true

4. Syntax of Conditionals
• if condition:
• # code block
• elif another_condition:
• # another block
• else:
• # fallback block

5. Example: Basic if
• x = 10
• if x > 5:
• print('x is greater than 5')

6. Example: if-else
• age = 16
• if age >= 18:
• print('You can vote')
• else:
• print('Too young to vote')

7. Example: if-elif-else
• marks = 75
• if marks >= 90:
• print('Grade: A')
• elif marks >= 60:
• print('Grade: B')
• else:
• print('Grade: C')

8. Using Logical Operators
• temperature = 30
• humidity = 70
• if temperature > 25 and humidity > 60:
• print('It feels hot and humid!')

9. Practice Questions
• 1. Check if a number is positive, negative, or
zero
• 2. Check if a year is a leap year
• 3. Grade calculator
• 4. Classify age as child, adult, or senior

10. Summary
• - Use if, elif, else for decision-making
• - Combine with logical operators for more
power
• - Indentation is crucial in Python!
