My experience with Packt has been wholly negative.

To give an example of what to expect, my experience with one particular book on Scientific Python: * most code examples wouldn't run without significant modification, mainly due to missing lines and multiple typos * some of the text was cryptic to the point of absurdity * topic coverage was unstructured, patchy and made no coherent sense overall * the website for the book was broken and I couldn't find any way to feed my corrections back to the author

Clearly Packt put no effort into quality assurance or editing. I would suggest you would be better off waiting for something from a more reliable publisher: such poorly edited books will just waste your time.
