I read the question and answers submitted by other Users and have a question. Does the book includes only basic example and code snippets or examples of Complex program/advance programming?
I am currently into Python these days but hopefully reading Go language Pro's over other languages and its simplicity i might give it a try and see what can be explored.
The examples tend to be simpler, but with good reason... The Head First series editors have always encouraged authors to keep code samples to a length that can fit on a single page. When readers can see the entire program at once without flipping back and forth between pages, they can understand it more quickly, more thoroughly, and with less work.
Every sample in Head First Go is a fully-working program, though, and many teach all the components you need to make useful utilities of your own! If you'd like to browse them, they're available for download at https://headfirstgo.com.
