# Variables in python 3.

**Day 2**

## **Variable:**

A variable lets you store a value by assigning it to a name. The name can be used to refer to the value later in the program. 

For example, in game development, you would use a variable to store the points of the player. What’s the point of playing if you don’t know who’s winning right!

To assign a variable, use one equals sign

**-->** Naming your variables is pretty flexible. You can use letters, numbers, and underscores in variable names. But you can’t use special symbols, or start the name with a number.
