Programming and problem solving with Python

Description

This book aims at providing students thorough knowhow of Python programming language. It will familiarize them with the concepts of Python programming, its application in programming as well as advantages and disadvantages over other programming languages. The book covers all the fundamental and theoretical concepts of Python comprehensively. Apart from touching upon the concepts of Python programming, equal weightage in given on the implementation of these concepts in writing efficient python codes and solve problems using the same.
