(Thedescending=Truebit is called anoptional argument. It has a default value ofFalse, so when you explicitly tell the functiondescending=True, then the function will sort in descending order.)

sort

Some details about sort:

1. The first argument tosortis the name of a column to sort by.
2. If the column has text in it,sortwill sort alphabetically; if the column has numbers, it will sort numerically.
3. The value offarmers_markets_locations.sort("x")is acopyoffarmers_markets_locations; thefarmers_markets_locationstable doesn't get modified. For example, if we calledfarmers_markets_locations.sort("x"), then runningfarmers_markets_locationsby itself would still return the unsorted table.
4. Rows always stick together when a table is sorted. It wouldn't make sense to sort just one column and leave the other columns alone. For example, in this case, if we sorted just thexcolumn, the farmers' markets would all end up with the wrong longitudes.

Question 3.5.Create a version offarmers_markets_locationsthat's sorted bylatitude (y), with the largest latitudes first. Call itfarmers_markets_locations_by_latitude.
