"Section 6.9 of your textbook ("Debugging") lists three possibilities to consider if a function is not working. Describe each possibility in your own words. Define "precondition" and "postcondition" as part of your description. Create your own example of each possibility in Python code. List the code for each example, along with sample output from trying to run it."
