Duplicate "it" in the sentence below, looks like a typo:

"That means that _it_ in general it doesn't care..."

Should be "That means that in general it doesn't care..."

For instance, if you don't mind being angrily accused of... **the text after this is italicized and strangely formatted**

Note from the Author or Editor:
formatting mistake, the hyperlink got formatted wrong

The URL https://www.nytimes.com/2014/06/30/technology/facebook-tinkers-with-users-emotions-in-news-feed-experiment-stirring-outcry.html should be hyperlinked to "experimenting on your users" and italics unnecessary, except for the word "causes"

first two function definitions

def total(xs: list) -> float:
return sum(total)

I think this should be

def total(xs: list) -> float:
return sum(xs)

Likewise for

def total(xs: List[float]) -> float:
return sum(total)

The argument for sum() should be xs rather than total.

P.S. Wonderful book, seems aimed right where I am -- unless I am totally wrong above, in which case I have some prep work to do.

Note from the Author or Editor:
the proposed fix (replacing "total" with "xs" in two places) is correct
