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

By: Dr. Basant Agarwal

Overview of this book

Choosing the right data structure is pivotal to optimizing the performance and scalability of applications. This new edition of Hands-On Data Structures and Algorithms with Python will expand your understanding of key structures, including stacks, queues, and lists, and also show you how to apply priority queues and heaps in applications. You’ll learn how to analyze and compare Python algorithms, and understand which algorithms should be used for a problem based on running time and computational complexity. You will also become confident organizing your code in a manageable, consistent, and scalable way, which will boost your productivity as a Python developer. By the end of this Python book, you’ll be able to manipulate the most important data structures and algorithms to more efficiently store, organize, and access data in your applications.

Installing Python

Python is preinstalled on Linux- and Mac-based operating systems. However, you will want to install the latest version of Python, which can be done on different operating systems as per the following instructions.

Windows operating system

For Windows, Python can be installed through an executable .exe file.

  1. Go to https://www.python.org/downloads/.
  2. Choose the latest version of Python—currently, it is 3.10.0—according to your architecture. If you have a 32-bit version of Windows, choose the 32-bit installer; otherwise, choose the 64-bit installer.
  3. Download the .exe file.
  4. Open the python-3.10.0.exe file.
  5. Make sure to check Add Python 3.10.0 to PATH.
  6. Click Install Now and then wait until the installation is complete; you can now use Python.
  7. To verify that Python is installed correctly, open the Command Prompt and type the python -–version command. It should output Python 3.10.0.

Linux-based operating systems

To install Python on a Linux machine, take the following steps:

  1. Check whether you have Python preinstalled by entering the python --version command in the terminal.
  2. If you do have not a version of Python, then install it through the following command:
    sudo apt-get install python3.10
    
  3. Now, verify that you have installed Python correctly by typing the python3.10 --version command in the terminal. It should output Python 3.10.0.

Mac operating system

To install Python on a Mac, take the following steps:

  1. Go to https://www.python.org/downloads/.
  2. Download and open the installer file for Python 3.10.0.
  3. Click Install Now.
  4. To verify that Python is installed correctly, open the terminal and type python –version. It should output Python 3.10.0.
