1. What is a Nested If?

A nested if means an if statement inside another if statement.

In simple words:
👉 Python checks one condition
👉 If it is True, Python checks another condition inside it

2. Why Use Nested If?

We use nested if when:

• One condition depends on another

• We want step-by-step checking

3. Simple Nested If Example

Example

👉 Second if runs only if the first is true.

4. Nested If with Else

Same using logical operator:

👉 Logical operators are cleaner sometimes.

9. Important Rule: Indentation

Indentation shows which if is inside which.

❌ Wrong

✔ Correct

10. Common Beginner Mistakes

❌ Too Many Nested Ifs

👉 Avoid deep nesting if possible.

❌ Forgetting Indentation

11. Simple Practice Examples

Example 1: Result Check

Example 2: Weather Check

Example 3: Bank Login

12. Summary (Python Nested If)

✔ If inside another if

✔ Indentation is very important
✔ Logical operators can replace nested if
✔ Useful in real-life decisions
