In a file called q5.py, write a function called wordsListO that takes a string as input. This string consists of a body of text. We want to make lists of all
the words in the text that are the same length. Again, we use the same notion of a
word as the previous questions. You will need to use a dictionary that has lengths
as the keys and lists of words (with that length) as their values. Each word in the
text should be put into a list within the dictionary of words with the same length.
That is, all 2-letter words are put into one list, all 3-letter words are put into
another list, etc. Your function will return a dictionary containing all the lists that were created.

7.23 main lab 7 - online shopping cart background this main lab extends the earlier prep lab "online shopping cart part 1". (you should save this as a separate project from the earlier prep lab). you will create an on-line shopping cart like you might use for your on-line purchases. the goal is to become comfortable with setting up classes and using objects. requirements this lab can be done individually or as pair programming. expanded itemtopurchase class (15 points) extend the itemtopurchase class as follows. we will not do unit testing in this lab so we will not be giving you the names of the member functions. create good ones on your own. create a parameterized constructor to assign item name, item description, item price, and item quantity (default values of "none" for name and description, and 0 for price and quantity). additional public member functions set an item description get an item description print the cost of an item - outputs the item name followed by the quantity, price, and subtotal (see example) print the description of an item - outputs the item name and description (see example) additional private data members a string for the description of the item. example output of the function which prints the cost of an item: bottled water 10 @ $1.50 = $15.00 example output of the function which prints the item description:
