Assignment 9

Question

Write and document a Python script statsGUI.py which implements a GUI (using functions in module Tkinter) for the vector statistics derivation and display system described in Assignment 7. This GUI should have the following basic capabilities:
• List available commands and their formats via some sort of help mechanism.
• Invoke each command specified in Assignment 7 in a designated command-entry area of the GUI.
• Display outputs of invoked commands in a designated output-display area of the GUI.
• When necessary, display error messages in a designated error-display area of the GUI.
• Exit GUI

Your GUI should allow any number of each of operations above (except the last) in one GUI session. You may assume that all requested vector and matrix files exist and are valid and that all requested rows, columns, and diagonals of matrices exist, i,.e., no error-checking or handling above that already specified in Assignment 7 is required. To obtain the up to 50% bonus marks, implement additional abilities such as (but not restricted to):

• Extra error-handling with respect to vector and/or matrix file and/or requested row, column, or diagonal vector from matrix file existence.
• Other basic statistics operations on individual or groups of vectors.
• Graphical displays of vector statistics and/or comparisons, e.g., scatter-plot of 2-vector comparison with best-fit line.
• Recall operation-application history of current GUI session.
• Super tricked-out overall GUI design.

Decisions on bonus marks will be made by your marker and cannot be disputed.

Hints

You may find it useful to have a number of buttons with associated callback functions to implement the various operations.

Submission

Please hand in printed copies of all of your Python script files as well as a short (up to 1 page) file README.txt describing the features of your GUI and how to invoke/use them. You must also submit these files electronically using the submit-assignment command. Note that each script file must have the following comment block at the top, where the X's are replaced with the appropriate information, followed by a docstring briefly describing the program in that script. For instance, my script for this assignment would begin with the following comment block:

You do not have to develop your code on our CS departmental systems. However, as your code will be compiled and tested on our CS departmental systems as part of the assignment marking process, you should ensure that your code compiles and runs correctly on at least one of these systems.
