Lesson details
Key learning points
- Lists are data structures that can store multiple related items in Python.
- Values held in a list are ordered by index number, with the first item in the list being stored at index [0].
- List items can be directly accessed by specifying the index value.
Keywords
Selection - used when there is more than one possible path for a program to follow
List - a collection of data in a particular sequence
Data structure - an organised way to store data for easy use
Index - the location of an item or element in a list or string
Common misconception
A list index starts at 1 as that is the first element in the list and should be counted as the first item.
In most programming languages, list indexing is zero-based, which means the index starts at 0. The number indicates the position before the value is seen.
Equipment
All pupils require access to devices that can edit and run Python programs. Starter code files are available to copy or use directly via the Raspberry Pi Foundation's Code Editor.
