Fixing a data type

We saw in the previous exercise that the is_arrested column currently has the object data type. In this exercise, we'll change the data type to bool, which is the most suitable type for a column containing True and False values.

Fixing the data type will enable us to use mathematical operations on the is_arrested column that would not be possible otherwise.

Anleitung zur Übung

Examine the head of the is_arrested column to verify that it contains True and False values and to check the column's data type.
Use the .astype() method to convert is_arrested to a bool column.
Check the new data type of is_arrested to confirm that it is now a bool column.
