Suggest a cleaner way to handle Python exceptions?

Python Server Side Programming Programming

I have the following code where there is repetitive clean up involved.

try:
    #some code here
except ValueError , e :
    cleanup_p()
    cleanup_q()
    handle_ValueError()
except IOError , e :
    cleanup_m()
    cleanup_n()
    handle_IOError()

Is there an elegant way of handling repetitive clean-ups in exception handling?

We can use the finally clause to clean up whether an exception is thrown or not:

try:
  #some code here
except:
  handle_exception()
finally:
  do_cleanup()

If the cleanup is to be done in the event of an exception, we can code like this:

should_cleanup = True
try:
  #some code here
  should_cleanup = False
except:
  handle_exception()
finally:
  if should_cleanup():
    do_cleanup()
