Project 2: Text Analyzer Overview In this project, you will create a utility program that reads a passage of text and computes various statistics such as number of characters, number of words, average word length, and how often each word appears. Part of the code (the user interface) will be provided for you. Instructions: 1. Download the starter code from Blackboard (project2starter.py) 2. Run the starter code to make sure it works on your machine. A window with a text box and a button should appear. If it does not, please contact the instructor. 3. Read over the Sample Run to get an understanding of what the project is supposed to do. 4. See the Detailed Description for more details on implementing the necessary functionality (i.e. getting the button to actually do something) The design document for this project is due on Friday, September 22, 2017, at 5 PM.
