Truncating strings

In the previous exercise, you calculated the length of the description column and noticed that the number of characters varied but most of the results were over 75 characters. There will be many times when you need to truncate a text column to a certain length to meet specific criteria for an application. In this exercise, we will practice getting the first 50 characters of the description column.
