Python programming- finally

Using finally in error handling

The statements in finally block still execute although some errors are raised or not. The common use of finally block is to clear objects from memory.
>>> def sumrange(lst):
            for i in lst:
            return result
>>> lst=range(1,10)
>>> try:
except Excepton:print 'Error(s) in sum operation'
            del lst
            print 'The object has been cleared.'
The object has been cleared.
Note: You can use Exception class to catch any errors that you are not sure about.
