Basic Python Data Structures

Major Python Data Structures

1. Lists

2. Tuples

3. Dictionaries

4. Sets

1. Lists

List can contain values of any type as a sequence. Arrays are usually implemented in python using Lists.

A single list can contain String, integer, float at once.

Lists are mutable. Meaning, elements can be inserted, deleted or modified.

2. Tuples

Tuples are immutable. Once created, insert, delete or modify operations cannot be done on tuple elements.

Immutability makes it useful while passing arguments to the function parameters in python ie., to *args.

3. Dictionaries

Dictionary stores key-value pairs. Values could be of different data types and even contain duplicates but the key should be unique and of string data type.

Dictionary can be used to implement Hash maps.

4. Sets

Sets is unordered and immutable. It can store elements of different data types at once. Once created, a set can be modified.

Sets are usually used where mathematical set operations such as union or intersections are to be used on the data.
