Mathematical operations in data structures

Computing

Creating lists in Python

Python list operations

Iterating through data structures

Using for loops to iterate data structures

Data structure projects in Python

In this unit pupils will discover how data is represented and processed in sequences, such as lists and strings. They will cover a spectrum of operations on sequences of data, that range from accessing an individual element to manipulating the entire sequence though real world practical activites.

Python programming with sequences of data

a symbol or word that instructs the computer to perform a calculation

to repeat a block of code a specific number of times

What is the primary purpose of a for loop in Python?

What is the index of the second item in a list?

What can be used to perform calculations in Python?

Items must be copied to a new variable first.

Operations are only for lists with numbers.

Operations can be performed directly on list items.

Items need to be converted to strings for operations.

Which statement about performing mathematical operations on list items in Python is true?

What does the `shuffle()` function do to a list in Python?

 a collection of data in a particular sequence

What is the index number that holds the first item in a Python list?

What method would you use to add an item to a list?

What is the term for repeating a sequence of instructions?
