🐍 Python Basics: Mastering if, elif, and else Statements

1. The if Statement

The if statement allows you to run a block of code only if a condition is true.

Output:

You are an adult!

• The condition age >= 18) is evaluated.

• If it’s True, the indented block runs.

• If it’s False, Python skips the block.

2. The else Statement

The else statement runs when the if condition is false.

Output:

You are a minor.

Think of else as a fallback—it runs when no if conditions are met.

3. The elif Statement

Sometimes, you need multiple conditions. That’s where elif (short for “else if”) comes in!

Output:

You are a teenager.

Python checks conditions in order:

1. If age >= 18 → False, move to elif.

2. If age >= 13 → True, run the block.

3. If none are True, the else block runs.

4. Using Multiple elif Statements

You can have multiple elif statements for complex conditions:

Output:

Grade: B

Python stops checking once it finds a True condition—even if later conditions would also be true.

5. Using Logical Operators (and, or, not)

You can combine conditions using logical operators:

Output:

The weather is nice!

More examples:

• and → Both conditions must be True

• or → At least one condition must be True

• not → Reverses a condition

Output:

6. Best Practices for if Statements

✅ Keep conditions simple → Avoid overly complex logic inside if.

✅ Use elif instead of multiple if statements → This makes the code efficient.

✅ Use indentation properly → Python relies on indentation to define blocks.

🏆 Conclusion

if, elif, and else statements control the flow of your program by making decisions based on conditions. Mastering these statements is key to writing dynamic Python programs!
