Preface
It gives us an immense pleasure to bring out a book entitled ‘Conceptualizing Python in Google COLAB’.
The goal of this book is to introduce you to the topic and get you started on your journey to application
development using Python. There are many books, websites, online courses, tutorials etc. on Python. The
current book is different in that it does not provide a lengthy tutorial introduction to a particular aspect
Python, but gives the practical inputs for learning Python in a simple and effective way. The book offers
first hand acquaintance with the Python language and the new constructs added to the language in order to
render it safe, clean and robust. It aims to provide comprehensive material on Python
How is this Book Organized:
This book can serve as textbook for post graduates and reference for any computer graduate. It will also
provide easy reference for Computer Professionals who wants to begin their career in Machine Learning
using Python. This book is precisely organized into twelve chapters. Each chapter has been carefully
developed with the help of several implemented concepts. Dedicated efforts have been put in to ensure that
every concept of Python discussed in this book is explained with help of relevant commands and
screenshots of the outputs have been included. Chapter 1 focuses on development environment offered by
Google COLAB. Chapters 2 through 4 cover the Python language fundamentals focusing on control and
iterative statements, operators along with their applications in basic programs. Python employs blended
programming paradigm in which it is procedural, object-oriented and functional. The best part of all
programming languages reside in a single platform. Chapter 5 focuses on functions in Python with a special
emphasis on Lambda functions. Advanced Python programming concepts such as iterators, closures,
decorators, generators are covered at depth in Chapter 6 and 7. A good and in-depth knowledge of
exception handling enables in writing a reliable and robust code. To cater to this need Chapter 8 unleashes
the salient features of exception handling in Python. Data persistence through file handling is covered in
Chapter 9. Due to the wide application of Regular expressions in pattern matching, Chapter 10 is fully
devoted to understanding of regular expression in Python. Different types of common errors that might
creep in during the execution of a Python program are summarized in Chapter 11. Final Chapter 12 is
devoted to implementation of object oriented concepts in Python. The case study based on object oriented
concept is discussed at depth and implemented in Appendix A.
The part of the content of this book is derived from different sources which are listed at the end in a
‘references’ section.
