Write a function named words_in_both that takes two strings as parameters and returns a set of the words contained in both strings. You can assume all characters are letters or spaces. Capitalization shouldn't matter: "to", "To", "tO", and "TO" should all count as the same word. The words in the set should be all lower-case. For example, if one string contains "To", and the other string contains "TO", then the set should contain "to".

You can use Python's split() funciton, which breaks up a string into a list of strings. For example:

sentence = 'Not the comfy chair!' print(sentence.split()) ['Not', 'the', 'comfy', 'chair!'] 

Here's one simple example of how words_in_both() might be used:

common_words = words_in_both('She's a jack of all trades', 'Jack was tallest of all') 

The file must be named: words_in_both.py
