Write a function called shorter_than(n, wordlist) that takes as inputs an integer n and a list of strings wordlist, and that uses a list comprehension to construct and return a list consisting of all words from wordlist that are shorter than n. For example:

>>> shorter_than(4, ['only', 'recursion', 'on', 'the', 'brain']) result: ['on', 'the'] >>> cities = ['Boston', 'Chicago', 'Washington', 'Houston'] >>> shorter_than(7, cities) result: ['Boston'] >>> shorter_than(6, cities) [] 

Hint: Your list comprehension will need an if clause.
