Lesson 3

Ciphers and text-based programming

Introduction

Students are introduced to text-based programming by exploring JavaScript code before creating a Caesar cipher in Python.

Learning objectives

  • To develop practical understanding of text-based programming
  • To understand and use selection, variables and functions
