Question

What will be an ideal response?

Answer 1

```
# Re-raising exceptions.

import math
import random

class ResultList( list ):
"""Class that keeps track of mathematical results"""

def recordResult( self, function, argument ):
"""Append result of function to list"""

# apply function and append result to list
try:
result = function( argument )
self.append( result )
except Exception, exception:
self.append( exception )
raise exception

# main program

# create ResultList instance
resultList = ResultList()

print "Computing 10 cases..."
print "---------------------"

# compute 10 results
for i in range( 10 ):

# print test number and record result
try:
print "Test %d:" % ( i + 1 ),
resultList.recordResult(
math.sqrt, random.randrange( -2, 5 ) )
print "SUCCESS"

# print status if an error occurs
except ValueError:
print "ERROR"

print "\nPrint results..."
print "-------------------"

# iterate over results list and print results
for result in resultList:
print result
```
Computing 10 cases...
---------------------
Test 1: SUCCESS
Test 2: SUCCESS
Test 3: ERROR
Test 4: SUCCESS
Test 5: SUCCESS
Test 6: ERROR
Test 7: SUCCESS
Test 8: SUCCESS
Test 9: SUCCESS
Test 10: ERROR
Print results...
