GE3151 PROBLEM SOLVING AND PYTHON PROGRAMMING L T P C
3 0 0 3
COURSE OBJECTIVES:
To understand the basics of algorithmic problem solving.
To learn to solve problems using Python conditionals and loops.
To define Python functions and use function calls to solve problems.
To use Python data structures - lists, tuples, dictionaries to represent complex data.
To do input/output with files in Python.
UNIT I COMPUTATIONAL THINKING AND PROBLEM SOLVING
9
Fundamentals of Computing – Identification of Computational Problems -Algorithms, building blocks
of algorithms (statements, state, control flow, functions), notation (pseudo code, flow chart,
programming language), algorithmic problem solving, simple strategies for developing algorithms
(iteration, recursion). Illustrative problems: find minimum in a list, insert a card in a list of sorted
cards, guess an integer number in a range, Towers of Hanoi.
UNIT II DATA TYPES, EXPRESSIONS, STATEMENTS
9
Python interpreter and interactive mode, debugging; values and types: int, float, boolean,
string, and list; variables, expressions, statements, tuple assignment, precedence of operators,
comments; Illustrative programs: exchange the values of two variables, circulate the values of n
variables, distance between two points.
UNIT III CONTROL FLOW, FUNCTIONS, STRINGS
9
Conditionals: Boolean values and operators, conditional (if), alternative (if-else), chained conditional
(if-elif-else); Iteration: state, while, for, break, continue, pass; Fruitful functions: return values,
parameters, local and global scope, function composition, recursion; Strings: string slices,
immutability, string functions and
methods, string module; Lists as arrays. Illustrative programs: square root, gcd, exponentiation,
sum an array of numbers, linear search, binary search.
UNIT IV LISTS, TUPLES, DICTIONARIES
9
Lists: list operations, list slices, list methods, list loop, mutability, aliasing, cloning lists, list
parameters; Tuples: tuple assignment, tuple as return value; Dictionaries: operations and methods;
advanced list processing - list comprehension; Illustrative programs: simple sorting, histogram,
Students marks statement, Retail bill preparation.
UNIT V FILES, MODULES, PACKAGES
9
Files and exception: text files, reading and writing files, format operator; command line arguments,
errors and exceptions, handling exceptions, modules, packages; Illustrative programs: word count,
copy file, Voter’s age validation, Marks range validation (0-100).
TOTAL : 45 PERIODS
COURSE OUTCOMES:
