Store data with variables.

What are Variables?

Variables hold data. Think of them as labeled boxes.

Creating Variables

```python name = "John" age = 25 city = "New York" is_student = True

print(name) # Output: John print(age) # Output: 25 ```

Variable Types

```python # String (text) greeting = "Hello"

Integer (whole number) count = 10

Float (decimal) price = 19.99

Boolean (True/False) is_active = True ```

Changing Variables

```python score = 0 score = 10 score = score + 5 # Now score is 15 ```

Remember

- No need to declare type - Names are case-sensitive - Use meaningful names
