About this previous year paper
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.
