Course Description:

Python is a language with a simple syntax, and a powerful set of libraries. It is an interpreted

language, with a rich programming environment. While it is easy for beginners to learn, it is widely

used in many scientific areas for data exploration. This course is an introduction to the Python

programming language for students without prior programming experience. This course provides

knowledge on how to implement programs in python language and to solve computational problems

using the various programming constructs including data structures, functions, string handling

mechanisms and file handling concepts.

Course Objectives:

1. Learn Python programming constructs.

2. Implement Python programs with conditional structures and loops.

3. Use functions for structuring Python programs.

4. Handle compound data using Python lists, tuples, and dictionaries.

5. Manipulate data using files handling in Python.

UNIT-I

Introduction: Algorithms, building blocks of algorithms (flow chart), History of Python, features of

Python Programming, Running Python Scripts, Variables, Assignment, Keywords, Input-Output,

Indentation. Data Types – Integers, Strings, Boolean.

a) Develop a flowchart for the various arithmetic operations on numbers.

b) Develop a flowchart to check whether the number is positive or negative.

c) Develop a flowchart for finding whether a given number is even or odd.

d) Develop a flowchart for finding biggest number among three numbers.

e) Develop a flowchart for displaying reversal of a number.

f) Develop a flowchart to print factorial of a number using function.

g) Develop a flowchart to generate prime numbers series up to N using function.

h) Develop a flowchart to check given number is palindrome or not using function.

i) Alexa travelled 150 kms by train. How much distance in miles she actually covered?

(12)

UNIT-II

Operators and Expressions: Operators- Arithmetic Operators, Comparison (Relational) Operators,

Assignment Operators, Logical Operators, Bitwise Operators, Membership Operators, Identity

Operators, Expressions and order of evaluations .Control Flow – if, if-elif-else, for,

while,break,continue,pass.

a) Swapping of two number with and without using temporary variable.

b) If the age of Ram, Sam, and Khan are input through the keyboard, write a python program to

determine the eldest and youngest of the three.

c) Develop a program that performs arithmetic operations (Addition, Subtraction, Multiplication,

and Division) on integers. Input the two integer values and operator for performing arithmetic

operation through keyboard. The operator codes are as follows:

 For code ‘+’, perform addition.

 For code ‘-‘, perform subtraction.

 For code ‘*’, perform multiplication.

 For code ‘/’, perform division.

d) Implement the python program to generate the multiplication table.

e) Implement Python program to find sum of natural numbers

f) If the first name of a student is input through the keyboard, write a program to display the

vowels and consonants present in his/her name.

g) The marks obtained by a student in 5 different subjects are input through the keyboard. Find

the average and print the student grade as per the MITS examination policy as shown below.

% OBTAINED GRADE

90 – 100 O (Outstanding)

80 – 89 A+ (Excellent)

70 – 79 A (Very Good)

60 – 69 B+ (Good)

50 – 59 B (Above)

45 – 49 C (Average)

40 – 44 P (Pass)

< 40 F (Fail)

h) Implement Python Script to generate prime numbers series up to N.

i) Given a number x, determine whether it is Armstrong number or not. Hint: For example, 371

is an Armstrong number since 3**3 + 7**3 + 1**3 = 371. Write a program to find all

Armstrong number in the range of 0 and 999.

one using function. (12)

UNIT-IV

String Handling -Modules: Creating modules, import statement, from.import statement, name

spacing-Files and Directories

a) Implement Python program to perform various operations on string using string libraries.

b) Implement Python program to remove punctuations from a given string.

c) Write a Python program to change the case of the given string (convert the string from lower

case to upper case). If the entered string is “computer”, your program should output

“COMPUTER” without using library functions.

d) Implement Python program to capitalize each word in a string. For example, the entered

sentence “god helps only people who work hard” to be converted as “God Helps Only People

Who Work Hard”

e) Write a Python script to display file contents.

f) Write a Python script to copy file contents from one file to another.

g) Write a Python script to combine two text files contents and print the number of lines,

sentences, words, characters and file size.
