Python contains a two-dimensional array representing the grades for a made-up course. Each row of the array represents a student, while each column of the array represents an assignment.

If the following two-dimensional array was contained within the python file:

gradebook = [[100, 100, 100, 96], [97, 87, 92, 88], [91, 90, 92, 91]]

Then you can think of the two-dimensional array as the following spreadsheet:

	Assignment 1	Assignment 2	Assignment 3	Assignment 4
Student 1:	100	100	100	96
Student 2:	97	87	92	88
Student 3:	91	90	92	91

And the program should print off the following when ran:

Assignment Averages: Assignment 1: 96.00 Assignment 2: 95.67 Assignment 3: 94.67 Assignment 4: 91.67 Student Averages: Student 1: 99.00 Student 2: 93.50 Student 3: 91.00

The output is to be nicely formatted. All averages are to be displayed to two decimal point (example: 97.67).
