Hi guys! I am the author of this book. Thanks heyalexej for posting this here. If there is anything I can help you guys with then kindly let me know. :)
You guys can donate me if you want to by buying the donation version of Intermediate Python from [@gumroad](https://gumroad.com/l/intermediate_python) :)
It is only for $10 but if you want to pay less then kindly let me know (pm) and I can give you a custom link.
Cheers!
