Class = int Slicing & Indexing are not allowed

Class = float Slicing & Indexing are not allowed

Class = str Allow Slicing & Indexing . Iterable

Class = bool Slicing & Indexing are not allowed

String ““

Boolean

Data Type List [ ]

Class : list

Dictionary {key : value } []

{}

Ordered, mutable, iterable, allow duplicate, indexing, slicing, Tuple ( ) Class : tuple Ordered, immutable, iterable, allow duplicate, indexing, slicing

Class : dict Keys are immutable, iterable Indxing and slicing are not allowed Set { }

()

{}

Class : set Unordered, mutable,iterable duplicate, indexing and slicing are not allowed

Elements of data don’t have a defined order, that order will change after running

Mutable means we can change the elements /items after it has been created Return sequence of items/elements

Insight Unordered

Mutable

Ordered

Slicing

Duplicate

Indexing Iterable

Iterable = Can be iterated by loop method

Elements of data have a defined order, that order will not change after running

Allow duplicate means data can have two items with the same value Positif index starts 0 from left side, while negative index starts-1 from right index

Python Operation Arithmetic

Assignment

Comparison

Mathematical Set

x+y

x += y

x>y

x-y

Union x|y

x -= y

x= y x
