# Python: Variables

Python has some simple variables.

myString = 'Hi' myWholeNumber = 7 myDecimalNumber = 4.5

Note that Python uses floor division when no floating point number is present. So if you want a float result use at least one float input.

n1 = 50 n2 = 4.0 print n1 / n2

The result would be **12.5**

## Operators

The following operators perform addition, subtraction, multiplication, division and exponentiation.

+ - * / **

When more then one operator is used it follows the **PEMDAS** rule (Parentheses, Exponentiation, Multiplication and Division, Addition and
Subtraction)
