Q.1 Compare and summarize four different coding styles supported by Python language. Four Coding Styles in Python • Procedural Style o Code written step by step. o Uses functions to perform tasks. o Simple and good for small programs. • Object-Oriented Style (OOP) o Uses classes and objects. o Supports concepts like inheritance,encapsulation and reusability. o Best for large applications. • Functional Style o Focus on pure functions (no side effects). o Uses map, filter, reduce, lambda. o Useful in data processing. • Scripting Style o Small programs written quickly. o Used for automation and file handling. o Best for system tasks. Q.2 Difference between List, Tuple and Dictionary in Python • List o Ordered collection of items. o Mutable → elements can be changed. o Allows duplicate values. o Example: o my_list = [10, 20, 30] o my_list[1] = 25 # list can be changed • Tuple o Ordered collection of items. o Immutable → elements cannot be changed after creation. o Allows duplicate values. o Example: o my_tuple = (10, 20, 30) o # my_tuple[1] = 25 not allowed
