Python MCQ Assignment: Data Types, Functions, and File Handling

This document presents a solved multiple-choice question (MCQ) assignment focused on core Python programming concepts. The assignment consists of 25 questions, each worth 4 marks, covering fundamental topics such as data types (including strings), functions (defining, parameters, return values, built-in functions), control flow (if/else statements, loops), file handling (reading, writing), and data structures (sets). The solution provides the correct answer for each question. This assignment is designed to test understanding of fundamental Python syntax, semantics, and common programming tasks. The questions assess the ability to predict code output, identify correct function definitions, and understand the behavior of different Python operations and methods. The assignment is suitable for students learning introductory Python programming. This assignment is available on Desklib, a platform providing AI-based study tools, offering students access to past papers and solved assignments to aid in their learning and exam preparation.
