Such error handling is often done using exception handling.
An (not to elegant) example:

--- Python code --
class MyError(Exception):
   pass

def foo():
   try:
     stuff=1
     bar=2
     if stuff != bar:
       raise MyError('Mismatch')

   except MyError, e:
     import sys
     print 'Error: "%s" happened in "%s"' % (
       str(e),
       str(sys.exc_info()[2].tb_frame.f_code.co_name)
     )

foo()
--- Python code end ---

The above code prints:
   Error: "Mismatch" happened in "foo"

The (sys.exc_info()[2].tb_frame.f_code.co_name) part is where the name 
is found.

Also look at asyncore and cgitb, they do some quite advanced error 
reporting.
