3 August Problem solving Methodologies: Understanding ofthe problem, solution for the problem, identifyingminimum number of inputs required for output,writing code to optimizing execution time andmemory storage, step by step solution for theproblem, breaking down solution into simple steps(modular approach), identification of arithmetic andlogical operations required for solution; ControlStructure- conditional control and looping (finite andinfinite).Problem Solving: Introduction toAlgorithms/Flowcharts.

UNIT 3: INTRODUCTION TO PYTHON

Getting Started: Introduction to Python- aninterpreted high level language, interactive mode andscript mode.Variables, Expressions and Statements: Values,

Variables and keywords; Operators and Operands inPython: (Arithmetic, relational and logical operators),operator precedence, Expressions and Statements(Assignment statement); Taking input (usingraw_input() and input()) and displaying output(print

statement); Putting Comments.
