Variables and data types in Python

This tutorial explains how to use variables in Python to store integers and strings. It also explains how to concatenate (join) strings in Python.

In programming, a variable is used to store data in a program. A variable can only store one value at a time, for example some text, a number, or a true/false value.

The different data types that a variable can store include:

  • string – this is text which can include letters, numbers, and other characters. String values are stored inside quotation marks
  • integer – whole numbers
  • float – numbers with a decimal point
  • boolean – a true/false value

Numbers and Math in Python

This tutorial explains how to use numbers and math functions in Python. To do math in Python, you can use a range of arithmetic operators including:

  • + for addition
  • – for subtraction
  • * for multiplication
  • / for division
  • % for modulus
  • **2 for squared, **3 for cubed, and so on

For example 5*5 will return the value 25. As you can see, it is just like writing any math expression.
