(SEM IV) THEORY EXAMINATION 2024-25 PYTHON PROGRAMMING

This document contains the complete B.Tech (Semester IV) Theory Examination 2024–25 question paper for Python Programming (BCC402). The paper spans three printed pages, carries 70 marks, and evaluates a student’s understanding of core Python concepts including variables, data types, operators, control statements, loops, functions, file handling, data structures, NumPy, Matplotlib, GUI programming (Tkinter), and package usage.

Section A – Short Conceptual Questions (14 Marks)

Section A includes seven 2-mark questions, each designed to test foundational Python knowledge. Topics include:

Definition of Python variables with examples (Page 1)

Explanation of basic operators in Python

Different Python data types with examples

Usage & declaration of numeric data types

A program demonstrating type-casting between int, float, string

Concept and use of if, elif, else along with an even/odd program

Difference between for loop and while loop with examples

These questions confirm a student's clarity on Python basics and syntax essentials.
 

Section B – Medium-Level Programming & Concepts (21 Marks)

Students must attempt any three out of five questions. This section focuses on loop control, data structures, and string operations:

Understanding break, continue, pass statements with examples

Program using for loop + dictionary to display student grades

Using nested loops to print a right-angled triangle of stars

Explanation of string slicing and string operations

Difference between tuples and lists with examples

These questions check practical Python application and logic-building skills.
 

Section C – Advanced Long Questions (35 Marks)

This section includes five main questions, each with two subparts. Students attempt one part from each.

Q3 – Dictionaries & String Methods

Program demonstrating CRUD (Create, Read, Update, Delete) operations on a dictionary

Explanation of common string methods with a program applying lower(), upper(), strip(), replace(), find(), and count() on

Q4 – Data Organization & File Modes

Organizing data using complex data types in Python

Explanation of file handling modes (r, w, a, rb, etc.)

Q5 – File Handling & seek() Method

Program to read/write data from a text file, explanation of readline() and readlines()

Purpose of seek() with a file-copy program

Q6 – NumPy & Matplotlib

Program to perform matrix operations using NumPy

Matplotlib-based line plot visualization using given data arrays

Q7 – GUI Programming & Pandas Package

Explanation of GUI programming in Python + Tkinter program to accept & display student data

Explanation of Python packages and uses of Pandas for data handling

These questions evaluate higher-level Python skills including file processing, visualization, package usage, and GUI development.
 

Summary

The Python Programming (BCC402) exam paper thoroughly tests:

Core Python syntax & data types

Control flow (if, else, loops)

Type casting & operators

Loop control statements

Lists, tuples, strings, dictionaries

File handling (read, write, seek, modes)

Nested loops & pattern generation

NumPy matrix operations

Matplotlib data visualization

Tkinter GUI programming

Pandas package usage

It is an excellent academic resource for engineering students learning Python fundamentals and practical coding skills.
