sort_values creates new DataFrame

You'll notice that sort_values call actually created a new DataFrame. If you want to permanently change the sort from the default (sorted by index), you can pass True as an argument to the inplace keyword parameter.

Hi givens,

I found this a curious statement too, as I read it, and so I ran this second line:

users.sort_values(by='balance', ascending=False).head()

users.head()   # my line

And sure enough, by default, users was still sorted alphabetically by index, the first row with an index of aaron

Neat, huh?
