When an exception occurs in Python, can you inspect the stack? Can you determine its depth? I’ve looked at the traceback module, but I can’t figure out how to use it.
My goal is to catch any exceptions that occur during the parsing of an eval expression, without catching exceptions thrown by any functions it may have called. Don’t berate me for using eval. It wasn’t my decision.
NOTE: I want to do this programmatically, not interactively.
You can use the inspect module which has some utility functions for tracing. Have a look at the overview of properties of the frame objects.
