Basics of python programming

Unit -I    ALGORITHMIC PROBLEM SOLVING

Algorithms, building blocks of algorithms, notation, algorithmic problem solving, simple strategies for developing algorithms.

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 AND EXPRESSIONS 

Python interpreter and interactive mode; values and types: int, float, Boolean, string, and list; variables, expressions, statements, tuple assignment, precedence of operators, comments; modules and functions, function definition and use, flow of execution, parameters and arguments.

Illustrative programs: exchange the values of two variables, circulate the values of n variables, distance between two points.

Unit -III     CONTROL FLOW AND FUNCTIONS  

Conditionals: Boolean values and operators, conditional, alternative, chained conditional; 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,  binary search, different patterns.

Unit -IV     DATA STRUCTURES: LISTS, TUPLES, DICTIONARIES 

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: selection sort, insertion sort, merge sort, histogram.

Unit -V      FILES, MODULES, PACKAGES 

 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
