Write a python 3 function named words_in_both that takes two strings as parameters and returns a set of only those words that appear 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". 1.Use python's set intersection operator in your code.
2.Use Python's split() function, 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 is a jack of all trades", 'Jack was tallest of all')

Jason, samantha, ravi, sheila, and ankit are preparing for an upcoming marathon. each day of the week, they run a certain number of miles and write them into a notebook. at the end of the week, they would like to know the number of miles run each day, the total miles for the week, and average miles run each day. write a program to them analyze their data. your program must contain parallel arrays: an array to store the names of the runners and a two-dimensional array of five rows and seven columns to store the number of miles run by each runner each day. furthermore, your program must contain at least the following functions: a function to read and store the runners’ names and the numbers of miles run each day; a function to find the total miles run by each runner and the average number of miles run each day; and a function to output the results. (you may assume that the input data is stored in a file and each line of data is in the following form: runnername milesday1 milesday2 milesday3 milesday4 milesday5 milesday6 milesday7.)
