To get the most out of this book

You should be comfortable coding in Python, with some familiarity with Matplotlib, NumPy, and pandas. The book covers a wide variety of libraries, and the first chapter will show you how to create different virtual environments for Python development. Working knowledge of the Python programming language will assist with understanding the key concepts covered in this book. It is recommended, but not required, to install either Anaconda, Miniconda, or Miniforge. Throughout the chapters, you will see instructions using either pip or Conda.

Alternatively, you can use Colab, and all you need is a browser.

Software/hardware covered in the book	Operating system requirements
Python 3.8/3.9+	Windows, macOS, or Linux
JupyterLab or the Jupyter Notebook	Windows, macOS, or Linux

In Chapter 3, Reading Time Series Data from Databases, and Chapter 5, Persisting Time Series Data to Databases, you will be working with different databases, including PostgreSQL, MySQL, InfluxDB, and MongoDB. If you do not have access to such databases, you can install them locally on your machine or use Docker and download the appropriate image using docker pull to download images from Docker Hub https://hub.docker.com – for example, docker pull influxdb to download InfluxDB. You can download Docker from the official page here: https://docs.docker.com/get-docker/.

Alternatively, you can explore hosted services such as Aiven https://aiven.io, which offers a 30-day trial and supports PostgreSQL, MySQL, and InfluxDB. For the recipes using AWS Redshift and Snowflake, you will need to have a subscription. You can subscribe to the AWS free tier here: https://aws.amazon.com/free. You can subscribe for a 30-day Snowflake trial here: https://signup.snowflake.com.

Similarly, in Chapter 2, Reading Time Series Data from Files, and Chapter 4, Persisting Time Series Data to Files, you will learn how to read and write data to AWS S3 buckets. This will require an AWS service subscription and should be covered under the free tier. For a list of all services covered under the free tier, you can visit the official page here: https://aws.amazon.com/free.

If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book's GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.

To get the most value out of this book, it is important that you continue to experiment with the recipes further using different time series data. Throughout the recipes, you will see a recurring theme in which multiple time series datasets are used. This is done deliberately so that you can observe how the results vary on different data. You are encouraged to continue with that theme on your own.
