ICT SECOND QUARTER EXAM

Sets

A collection data type made up of unordered elements

Curly Braces or {}

To specify sets you can use the

set()

To create sets you can use

len()

To check length you can use

add()

To add elements you can use

remove()

To delete elements you can use

in keyword, it will return a Boolean value

To check if a set contains a specific value use

Union (Vertical Bar)

Creates a union of two sets

Intersection (Ampersand&)

Gets the common elements between sets

Difference (-)

Gets the elements of the first set that are not in the second set

Exclusive (Caret^)

Gets all the elements in both sets except the intersecting values

Subset (<=)

Checks if the elements of first set are found in the second

Proper Subset (<)

Checks if the second set contains all the elements of the first and more

Superset (>=)

Checks if all the elements of the second set are found in the first

Proper Superset (>)

Checks if the first set contains all the elements of the second and more

Frozensets

Sets with immutable values

frozenset()

To specify a frozensets use

Dictionaries

A collection data type that consists of key and value pairs

dict()

Loops

It is when programming tasks can be repetitive.

While

keyword allows us to execute code over and over

for and in

To create loops we can use

break keyword

When you want to loop something indefinitely until conditionals met use

continue keywords

skips running the code for an iteration

range()

To create a sequence of numbers use

input()

To allow some interactions with a user use
