What does varible mean?

A variable is a container that holds a value. It's like a box that you can put something in and take it out later. In programming, variables are used to store data that can be used and changed throughout a program.

Here's a breakdown:

Key Concepts

* Name: A variable has a name that you use to refer to it. Think of this as a label on the box.

* Data Type: Variables hold specific types of data, like numbers, text (strings), or booleans (true/false). This helps the program understand how to use the data.

* Value: The actual information stored in the variable. This is the content of the box.

* Mutability: Some variables can have their values changed (mutable), while others can only be assigned a value once (immutable).

Example:

Let's say you have a variable named `age` that stores a person's age:

```

age = 25

```

* Name: `age`

* Data Type: Integer (a whole number)

* Value: 25

Now you can use the variable `age` in your program to perform calculations or display the age.

Why are variables important?

* Organization: They help you structure and manage data within your program.

* Flexibility: You can change the values of variables, making your programs more dynamic and adaptable.

* Reusability: You can use variables multiple times, avoiding the need to rewrite the same information.
