Problem Solving: Introduction to Algorithms/Flowcharts.
Unit 3: Introduction to Python (44 Theory + 36 Practical) Periods
Getting Started: Introduction to Python - an integrated high level language, interactive mode and script mode. Data types – Number (Integer – boolean, decimal, octal, hexadecimal; Floating point; Complex), none, Sequence (String,Tuples, List ) Sets, Mapping.
Mutable and Immutable Variables
Variables, Expressions and Statements: Values, Variables and Keywords; Operators and Operands in Python: (Arithmetic, Relational and Logical operators), Operator precedence, Expressions and Statements (Assignment statement); Taking input (using raw_input() and input() and displaying output(print statement); (single and multiple line) prints with escape sequence and various formats; Putting Comments.
Functions: Importing Modules (entire module or selected objects), invoking built in functions, functions from math module (for e.g. ceil, floor, fabs, exp, log, log10, pow, sqrt, cos, sin, tan, degrees, radians, factorial,trunc,fmod),functions from random module (uniform, random, randint choice shuffle). Function from datetime module (date, time, datetime, timedate), functions from remodule (compile, match, group, start, end, span, search, findall, finditer), compostion.
Defining functions, invoking functions, arguments and parameters, scope (local and global), passing parameters (default parameter values, keyword arguments), scope of variables, void functions and functions returning values, flow of execution,recursion.
Conditional and looping construct: if else statement while, for (range function), break, continue, else, pass, nested if, nested loops ,use of compound expression in conditional and looping construct.
Unit 4: Programming with Python (50 Theory + 48 Practical) Periods
