One of the most powerful things that makes computer programs so useful is their ability to repeat tasks quickly and efficiently. Iteration means controlling how many times a section of code will repeat.

Almost every program needs to be able to store data. Variables are great for storing individual values but it’s often useful to be able to store and process lots of data in a particular order.

Lists let you store and use lots of data in one variable. This activity explains how to access data stored in a list; how to add and remove data; how to choose something at random from a list and how to sort a list.

There are three types of errors that you’ll come across when learning to program in python (or any language): syntax errors, runtime errors and logic errors.

Logic errors are often the hardest to find and fix so the aim of this activity is to help you recognize them, debug them and avoid making them wherever possible.
