   • Interpreter. Python is an interpreted programming language. This means that it needs a different program (called an interpreter) to read and execute the source code.
   • Program. A program is a set of instructions that a computer uses to perform a specific action. Sometimes it's compared to a recipe with variables as ingredients and functions as instructions.
   • Variable. 'Variable' is a crucial term in every programming language, not just Python. If you're already familiar with variables from another programming language, you'll know how to use them in Python.
