Hands-On Data Structures and Algorithms with Python - Second Edition

Overview of this book

Data structures allow you to store and organize data efficiently. They are critical to any problem, provide a complete solution, and act like reusable code. Hands-On Data Structures and Algorithms with Python teaches you the essential Python data structures and the most common algorithms for building easy and maintainable applications. This book helps you to understand the power of linked lists, double linked lists, and circular linked lists. You will learn to create complex data structures, such as graphs, stacks, and queues. As you make your way through the chapters, you will explore the application of binary searches and binary search trees, along with learning common techniques and structures used in tasks such as preprocessing, modeling, and transforming data. In the concluding chapters, you will get to grips with organizing your code in a manageable, consistent, and extendable way. You will also study how to bubble sort, selection sort, insertion sort, and merge sort algorithms in detail. By the end of the book, you will have learned how to build components that are easy to understand, debug, and use in different applications. You will get insights into Python implementation of all the important and relevant algorithms.

Technical requirements

In order to proceed with this chapter, you will need to install the following packages. These packages will be used to pre-process and visually represent the data being processed. Some of the packages also contain a well-written implementation of the algorithms that will operate on our data.

Preferably, these modules should be installed using pip. So, firstly, we need to install pip for Python 3 using the following commands:

  • sudo apt-get update
  • sudo apt-get install python3-pip

Furthermore, the following commands are to be run to install the numpy, scikit-learn, matplotlib, pandas, and textblob packages:

# pip3 install numpy
# pip3 install scikit-learn
# pip3 install matplotlib
# pip3 install pandas
# pip3 install textblob

If you are using the old version of Python (that is, Python 2), the packages can be installed using the same commands by replacing pip3...
