python Write a function named first_medium_last that accepts a single string as its parameter representing a person's first, middle and last name. The function should return the person's first name, followed by their middle initial, followed by their last name. For example, the call first_medium_last("Bartholomew JoJo Simpson") should return "Bartholomew J. Simpson". You may assume that the argument consists of exactly three words separated by single spaces.

Note that there should be a period (dot) after the middle initial.
