Programing Assignment Sample

Q1:

Answer :

Python lists are mutable, ordered collections of items that can store elements of various data types. Lists allow for modification, such as adding, removing, or changing elements, making them dynamic. Tuples, on the other hand, are immutable, meaning their elements cannot be altered once defined. This immutability makes tuples more memory-efficient and suitable for fixed data structures.

For example, a list can be used for tasks requiring frequent updates, such as managing to-do lists, while tuples are ideal for constant data, such as coordinates. Both support indexing, slicing, and iteration, but their primary distinction lies in their mutability.

Q1:

Answer :

Functions in Python are reusable blocks of code designed to perform specific tasks. They allow programmers to organize and simplify code, making it more readable and modular. Functions enhance code reusability by enabling the same functionality to be used multiple times without rewriting code. Python functions are defined using the [def] keyword, followed by the function name and parameters.

For example, a function to calculate the square of a number can be reused for various inputs. Functions can return values or modify data structures. They are essential for maintaining cleaner, more efficient codebases and are crucial for large-scale programming projects.

Q1:

Answer :

In Python, for loops iterate over a sequence (e.g., list, string, range) and are ideal when the number of iterations is predetermined. For example:

for i in range(5): print(i)

This prints numbers 0 to 4.
While loops execute as long as a specified condition is true and are suited for indefinite iteration. For instance:

i = 0 while i < 5: print(i) i += 1
This produces the same output. The primary distinction lies in control: for loops iterate over sequences, while while loops depend on condition checks, providing flexibility for varying scenarios.
