Lesson details

Key learning points

  1. In this lesson, we will find out about variables. We will learn about the purpose of variables, but also the technical aspects of creating variables to a uniform standard. Variable declaration is not used in Python, so a wider look at this through other programming languages will help us gain an insight into its meaning.
