.apply() function in every cell

As you saw in the lesson, you can use .apply() to map a function to every cell of the DataFrame, regardless the column or the row.

You're going to try it out on the poker_hands dataset. You will use .apply() to square every cell of the DataFrame. The native Python way to square a number n is n**2.
