python try raise for warnings

[ChetMeinzer]

Is it possible to define my own type of error and raise that based on spss syntax output?
For example, when a file is open on another computer and spss attempts to save over it, I’m getting the ‘_1’.  
But, I need this warning to trigger a ‘break’ or error that ends the ‘try:’

Also, is there a way around this all together.

Class WarningSave(Exception):
        def __init__(self, value):
                self.value = value
        def __str__(self):
                return repr(self.value)

No need to write an own error class. Probably this will do the trick:
�
try:
� � �  with open(filename, "wb") as f:
� � � � � � �  pass # add code here, but as little� code as possible
except IOError, e:
� � �  raise Exception(e)
else:
� � �  pass # optionally add code here that might also raise an IOError that you don't want to catch
finally:
� �  pass # optionally add code that you ALWAYS want to run.
