Accessing using .loc[] [2/3]

Not only you can get certain rows, but you can also get specific columns. To set column/columns you want to receive, pass it as the second parameter between square brackets of .loc[].

If you want to indicate only one column, just place its name. If you want to indicate several columns, you need to pass list of their names.

Note that the first parameter must be set, even if you don't want to indicate specific rows (use : instead).
