This is a homework assignment ....
I am trying to figure out how to take a string like the one below and do
the following; Remove the brackets Place commas in the white space
Also I am not supposed to do anything to the text that is in quotation marks.
I am new to Python by the way. We are week three in a college course. We

reformatting is like the one below:
