Write a basic list comprehension

In this exercise, you will practice what you've learned from the video about writing list comprehensions. You will write a list comprehension and identify the output that will be produced.

The following list has been pre-loaded in the environment.

doctor = ['house', 'cuddy', 'chase', 'thirteen', 'wilson']

How would a list comprehension that produces a list of the first character of each string in doctor look like? Note that the list comprehension uses doc as the iterator variable. What will the output be?
