Chapter 3. Dealing with Errors

Errors happen. Having code that can handle errors properly is essential. In this chapter, we will learn how to write code that gracefully handles errors in Maya Python. We'll start by understanding some technical basics about Python exceptions, such as the try/except statement and tracebacks. After that we will cover some golden rules for handling exceptions. We will map those guidelines to the way Maya works, and learn how to handle errors in Maya gracefully. We will use all of this knowledge to build a high-level error handler. The error handler will be an exception hook that will capture any relevant unhandled Python exception raised in Maya, and send an e-mail to us. Finally, we'll look at various ways to improve the error handler to make it useful in a production environment.
