Chapter 22 Debugging

Learning objectives:

• General strategy for finding and fixing errors.

• We are going to explore the traceback() function which helps us to locate exactly where an error occurred.

• We are going to explore how to pause the execution of a function and launch environment where we can interactively explore what’s happening.

• We are going to explore the challenging problem of debugging when you’re running code non-interactively.

• We are going to explore a handful of non-error problems that occasionally also need debugging.
