I’ve written a PEP proposing the addition of a new built-in function called debug(). Adding this to your code would invoke a debugger through the hook function sys.debughook().
Like the existing sys.displayhook() and sys.excepthook(), you can change sys.debughook() to point to the debugger of your choice. By default it invokes pdb.set_trace().
With this PEP instead of:
import pdb; pdb.set_trace()
you can write:
and you would drop into the debugger after foo() but before bar(). More rationale and details are provided in the PEP:
Unlike David, but like Larry, I have a prototype implementation:
