My experience with this book has been quite negative.
First and foremost, it depends crucially on data sets that are supposedly available from packt publishing. But I haven't been able to get them, because my purchase was from Amazon and not from Packt. I've sent them an email and we'll see if they ever respond. There is nothing more frustrating than getting a book about something you need to know, and finding that the book is useless until you complete some additional cycle to get the required data.
Second, there are lots of typos. And I mean *lots*. On the top of p.16, for example, I'm told to type in
plt.rcParams['lines.linewidth'] = '3
Of course, you have to set it to 3, not '3. On the previous page, I'm told that
plt.rcParams['lines.color'] = 'r'
will make the plot red. I have no idea why, but the plot came out blue.
There are multiple places where it is clear that English is not the author's first language. (He typically leaves out "the", which has no direct analog in Russian.)
At the end of Chapter 1, we are told to "see the back of this book for useful online resources." The only thing at the back of the book is a bunch of ads for other Packt Publishing titles. Shame on you!
Finally, the book is just poorly thought out. As an example, matplotlib has something alled a subplot. This is "introduced" on p.42, where you simply see plt.subplot(211) and plt.subplot(212) in code, without explanation. If you look in the index, you'll see that there is a section called "using subplots" on p.118-120. So I went and looked at that, where I found:
"If you are reading this book from the start, you are probably familiar with the subplot class ..."
Well, I was reading from the start, but it was never explained! And it's not eplained in this section, either.
In fact, *nothing* is explained. If you want to learn matplotlib, just go to the documentation at matplotlib.org. It's great.
Note added the next day: the packtpublishing web site now appears to be working, so I've bumped the review to 3 stars
