1. Introduction to Arrays
An array is a particular type of list data structure - we have a section on lists HERE. An array is used to store related data that are of the same type.
For example, say you wanted to store the names of players in a football team. The team has 11 players.
One way, is to store the names as independent variables,
player1 = "John Smith" player2 = "Harry Potter" player3 = "Jimmy Carr" ... and so on
So there would be eleven variables. The problem with this is it does not show that there is relationship between the names - that they are all part of the same football team. This is why an array data store is useful - it allows related data item to be stored as a group.
