(SEM III) THEORY EXAMINATION 2020-21 PYTHON PROGRAMMING

This document is the B.Tech (Semester III) Theory Examination 2020–2021 question paper for the subject Python Programming (KNC302) under Dr. A.P.J. Abdul Kalam Technical University (AKTU).
The exam duration is 3 hours, and the total marks are 100.
The uploaded paper contains 3 sections only: Section A, Section B, Section C, with further subdivisions inside Section C (Q3–Q7).

The paper spans 4 printed pages, all clearly structured with questions, marks, CO mapping, and Python code snippets.

SECTION A — 10 Short Questions (10 × 2 = 20 Marks)

As shown on Page 1, this section contains ten brief questions, each for 2 marks.

The questions check fundamental Python concepts:

Use of the raise statement

Writing a recursive reverse-print function

Behavior of range(s, e)

Use of the with statement (context managers)

Identifying incorrect multiple assignment statements

Operator precedence

Reading integer input from the user

Error due to string immutability in nested indexing

Output of a lambda expression

Use of the __lt__() function in Python classes

Every question is conceptual and designed to test Python basics.
 

SECTION B — Long Answer Questions (Any 3 × 10 = 30 Marks)

Section B appears on Page 2.
Students must attempt any three of the five 10-mark questions.

Topics include:

Writing a function removekth(s, k)

Computing average of list elements using try–except for empty list

Difference between linear search and binary search

Filtering values using list comprehension

Program to find all positive factors of a number

These questions require coding, explanation, and understanding of Python error handling, algorithms, and list operations.

SECTION C — Advanced / Applied Python Questions (Q3 to Q7, Each 10 Marks)

Section C appears across pages 2, 3, and 4.
Each question has two alternative parts, and the student must attempt one from each Q-number.

Q3 — Python Modules & Import System

(Shown on Page 2)

Creating a Python file that works both as a module and a standalone script
OR

Difference between

import library

from library import *

Q4 — Lists, Functions, Arguments

(Page 3)

Writing makePairs to pair elements from two lists
OR

Example using both keyword and default arguments in one function call

Q5 — Interpreter Concept & Short-Circuiting

(Page 3)

Why Python is called an interpreted language
OR

Short-circuit evaluation with program output for c or a

Q6 — Looping, Patterns, Number Theory

(Page 4)

Writing the triangle(N) pattern-printing program
OR

countSquares(N) to count perfect squares ≤ N

Q7 — Sequence Analysis & Searching

(Page 4)

alternating(lst) to check alternating even-odd pattern
OR

searchMany(s, x, k) to verify max. k occurrences of a value
