(R17A0554) PYTHON PROGRAMMING
OBJECTIVES:
 To read and write simple Python programs.
 To develop Python programs with conditionals and loops.
 To define Python functions and call them.
 To use Python data structures –- lists, tuples, dictionaries.
 To do input/output with files in Python.
UNIT I
INTRODUCTION DATA, EXPRESSIONS, STATEMENTS
Introduction to Python and installation, data types: Int, float, Boolean, string, and list; variables,
expressions, statements, precedence of operators, comments; modules, functions--- function and its
use, flow of execution, parameters and arguments.

UNIT II
CONTROL FLOW, LOOPS
Conditionals: Boolean values and operators, conditional (if), alternative (if-else), chained conditional
(if-elif-else); Iteration: while, for, break, continue.

UNIT III
FUNCTIONS, ARRAYS
Fruitful functions: return values, parameters, local and global scope, function composition,
recursion; Strings: string slices, immutability, string functions and methods, string module; Python
arrays, Access the Elements of an Array, array methods.

UNIT IV
LISTS, TUPLES, DICTIONARIES
Lists: list operations, list slices, list methods, list loop, mutability, aliasing, cloning lists, list
parameters, list comprehension; Tuples: tuple assignment, tuple as return value, tuple comprehension;
Dictionaries: operations and methods, comprehension;

UNIT V
FILES, EXCEPTIONS, MODULES, PACKAGES
Files and exception: text files, reading and writing files, command line arguments, errors and
exceptions, handling exceptions, modules (datetime, time, OS , calendar, math module), Explore
packages.

OUTCOMES: Upon completion of the course, students will be able to
 Read, write, execute by hand simple Python programs.
 Structure simple Python programs for solving problems.
 Decompose a Python program into functions.
 Represent compound data using Python lists, tuples, dictionaries.
 Read and write data from/to files in Python Programs
