Syntax, List Comprehensions, Lambda Functions, OOPs, Exception Handling, File I/O & Automation.
Python was created by Guido van Rossum and released in 1991. It is a high-level, interpreted, dynamically typed programming language known for its clean readability and extensive library ecosystem.
| Data Structure | Mutability | Syntax Example | Primary Use Case |
|---|---|---|---|
list | Mutable | [1, 2, "KKCC"] | Ordered collections, flexible element modification |
tuple | Immutable | (10, 20, 30) | Fixed constants, dictionary keys, record tuples |
dict | Mutable | {"name": "Java"} | Key-Value pair lookups, JSON representations |
set | Mutable | {1, 2, 3} | Unique element sets, mathematical set operations |
