What is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.

I'm only in the first chapter and I can already tell. This one is special. I've already learned so much! Looking forward to absorbing the rest.

Steve Karmeinsky May 12, 2021

Data Science (which includes machine learning etc) is all about working with data, sometimes a lot of data. As the saying goes, garbage in, garbage out and not all data sets are as clean as they should be, that may be due to data entry, formatting or other simple errors, however some data could be an outlier or statistical error and even spelling errors.This book shows the errors that can occur and methods to clean that data so it's useful for being processed so the messy data won't cause problems down the line. There are clear examples both of the types of data, how to manipulate it (code examples mainly python, but shell scripts, R and various data bases like SQQLite and others).If you're new (or even an old hand) at using data, then this book should be near you as a reference.

David did an incredible job covering the topics of data preparation and cleaning, I've learned quite a lot. Additionally, the outstanding choices of quotes, beautiful expressions, and anecdotes made this book an immensely enjoyable read. This goes directly to the list of book recommendations for my peers.

I think this is a good reference book for cleaning and handling numeric data, and includes some feature engineering as well. For images or text, one will probably want to consult another book or reference for more complete information. For example, the feature engineering and data preparation for NLP can get complex and there are many ways to do it (same for images). I think chapters 1, 2, 4, 5, and 6 would be most helpful for a DS beginner or intermediate practitioner. My favorite part was early in the book on the discussion of how spreadsheets can cause major problems.

Even if all you learn is some cool quotes (like the one in the headline), the UNIX tr(1) command, and what the word "chimera" is and how it relates to SQLite's data type enforcement, you never get cheated buying or reading one of this guy's books.Dr. Mertz is an intelligent, conscientious author who makes for a good read. His books always emphasize the mindset and thought process over rote memorization of code or cut and paste examples. But if you want to use the book that way, there are plenty of code examples you can use as templates. I am weak on Pandas and UNIX shell scripting, and totally ignorant of R. Just seeing how much you can do in a few lines of code throughout the book is encouraging.I'm about 2/3 of the way through the book. For me this is a great introduction to data science. Most of what I do is cleaning and transforming data. I think someone who is a data scientist by trade could still benefit a lot from this book - if only for review of the tools and, more importantly, methods available for cleaning and preparing data for the heavy lifting of data science.As a non-data scientist, I have still found plenty that is useful, even in the later data science focused chapters I'm reading now.Recommend.
