inconsistencies between tables and commands in 3.8 line [18]

[maxvolpi]

there are some inconsistencies in 3.8 on line [18].

I think the final .unstack() method should be removed from line [18] to produce the correct table.

the line I am talking about has this code:

[18] planets.groupby("method")["year"].describe().unstack()

The second edition is consistent between the command and the table produced, but I think what the author wanted was the table obtained in the first edition (page 164 of the printed ed), which is generated without using .unstack().
