Computational Thinking

Unfinished. These only include Year 10 content, sorry.

Computational thinking techniques

• Decomposition

  • Breaking down problems into smaller sub-problems

• Abstraction

  • Filtering out unnecessary ideas and details to focus on the important parts

Truth tables

Tables showing the value of different variables and how they contribute to an outcome

AND

Both A and B must be true

OR

Either A or B must be true

NOT

A must not be true

Relational operators

== - is equal to

> - is greater than

< - is less than

>= - is equal to or greater than

<= - is equal to or less than

Arithmetic operators

+ - addition

- - subtraction

* - multiplication

/ - division

** - exponentiation

% - remainder

// - floor division

Error types

Traceback = an exception with a message, callstack and where it occurred

• Syntax error

  • Part of the program does not follow the syntax

• Logic error

  • Program runs but does not work as it is meant to

• Runtime error

  • An error that occurs during program runtime

SSI

Sequence, selection, iteration

Data types

• String - convert with str()

• Integer - convert with int()

• Float - convert with float()

• Boolean - convert with bool()
