This unit introduces pupils to string-handling techniques, they will explore how a string can be iterated over using a loop and sliced to create substrings. Pupils will be introduced to arrays and lists and explore the differences between the two. They will manipulate with a variety of list methods.

Programming: strings and lists

the process of extracting a specific substring

a character set that represents each  character with a unique numerical value

a module that can generate random numbers, pick random items or shuffle a list

the process of joining strings together to create a new string

a string method that converts all letters in a string to lowercase

a string method that converts all letters in a string to uppercase

a data structure that has a fixed size in memory

a data structure that can grow or shrink to accommodate items

a static data structure that contains items of the same data type

a dynamic data structure that can contain items of different data types

add an item to a given position in a list

remove an item from a given index in a list

counting the number of occurrences of a given item

describes a list or array that has both columns and rows of values

a list or array that has both columns and rows of values

a sequence of instructions with an identifiable name that performs a specific task

hardware that attaches to the top of a Raspberry Pi computer and allows you to write programs that collect data from sensors — it also has an LED matrix for displaying output

a digital representation of the physical Sense HAT device

a single element of an image on a computer screen
