Using the Python debugger to trace method execution

Sometimes, application logs are not enough to figure out what is going wrong. Fortunately, we have the Python debugger available to us. This recipe shows how to insert a break point in a method and trace the execution by hand.

Getting ready

We will be reusing the export_stock_level() method shown in the two previous recipes. Be sure to have a copy at hand.

1. Edit the code of the method, and insert the line highlighted here:
