("Debugging")

Below is a list of three possibilities to consider if a function is not working.

There is something wrong with the arguments the function is getting; a precondition is violated.

There is something wrong with the function; a postcondition is violated.

There is something wrong with the return value or the way it is being used.

1.Describe each possibility above.

2.Define "precondition" and "postcondition" as part of your description.

3.Invent an example of each possibility in Python code. List the code for each example, along with sample output from trying to run it.
