COURSE DESCRIPTION

This manual is intended for the Second year students in the

subject of Programming with Python. This manual typically contains

practical/Lab Sessions related to Programming with Python covering

various aspects in order to enhance subject understanding.

Python is a general purpose, high-level programming language;

other high-level languages you might have heard of C++, PHP, and

Java. Virtually all modern programming languages make us of an

Integrated Development Environment (IDE), which allows the

creation, editing, testing, and saving of programs and modules. In

Python, the IDE is called IDLE (like many items in the language, this is a

reference to the British comedy group Monty Python, and in this case,

one of its members, Eric Idle).

Many modern languages use both processes. They are first

compiled into a lower level language, called byte code, and then

interpreted by a program called a virtual machine. Python uses both

processes, but because of the way programmers interact with it, it is

usually considered an interpreted language.

There are two ways to use the Python interpreter: shell mode and

script mode. In shell mode, you type Python statements into the Python

shell and the interpreter immediately prints the result. In script mode,

you type statements into the editor and save it in a file known as script.

The interpreter executes the code of the script.

Students are advised to thoroughly go through this manual rather

than only topic mentioned in the syllabus as practical aspects are

the key to understanding and conceptual visualization of theoretical

aspects covered in the books.

Also, this course is designed to review the concepts of Data

Structure using C, studied in previous semester and implement the

various algorithms related to different data structures. Good Luck for

your Enjoyable Laboratory Sessions.

CONTENT

This course is designed to provide the students the opportunity of

learning both – concepts of C, implementing algorithms of data

structures and programming with Python. This course is indented to

develop a deep understanding of various operations on data structure

such as searching, sorting, insertion, deletion and traversing and

provides students the idea of new programming language. Apart from

basic concepts, it helps to understand the concept of lists, tuples,

dictionaries and file handling.

OBJECTIVES

This course is designed to help students in:

Learning the concepts of different data structures using C.

Learning different sorting (Bubble Sort, Insertion Sort, Merge

Sort, Heap Sort, Quick Sort) and searching (Linear and Binary)

techniques using C.

Learning Linked List, Queue, Stack and their operations using C.

Write, debug and execute Python programs to solve various

problems.

RULES AND REGULATIONS

Students are required to strictly adhere to the following rules.

D

The students must complete the weekly activities/assignments

well in time (i.e., within the same week).

The students must maintain the Lab File of their completed

activities/assignments in the prescribed format (Appendix-1).

The students must get the completed weekly

activities/assignments checked and signed by the concerned

teachers in the Lab in the immediate succeeding week. Failing

which the activities/assignments for that week will be treated as

incomplete.

At least TEN (10) such timely completed and duly signed weekly

activities/assignments are compulsory, failing which students will

not be allowed to appear in the final Lab Examination.

The students need to submit the following three deliverables for

each exercise duly signed by the Teacher:

Algorithm

Flow Chart

Coding

Input /Output

Each question will be evaluated on a scale of 10 points, 4 for

Algorithm, 3 for Flow Chart and 3 for Coding part.

The students need to ensure that each question is assessed and

signed by the Teacher in the week/time.

Late submission would not be accepted after the due date.

Cooperate, collaborate and explore for the best individual

learning outcomes but copying is strictly prohibited.

in Shell and Script mode.

Note: When naming a Python program, a .py extension must be used. Failing

to do so will result in code that will not be recognized by the system as a Python

program.
