In this chapter we took a close at look at how Python's exceptions work. We defined what an exception is and learned that dealing with exceptions and errors is a fact of programming life. We examined in detail the interesting traceback type and the exc_info tuple. We learned a set of best practices for handling errors, and how those best practices apply to Maya.
