Well, for me the power of exceptions is that it lets me write much more 
concise code. For example, suppose I call a routine I wrote over and 
over, and I have to check for errors on each call. Then you have a long 
block of code like:
if err == 0:
   x1,err=somefunction(1)
if err == o:
   x2,err=somefunction(2)
...
...
but if somefunction just raises an exception on error, then you do
try:
   x1=somefunction(1)
   x2=somefunction(2)
   ...
   ...
except:
   blah blah

So for my uses, its handy to let things raise exceptions willy nilly in 
the lower level functions, and do the catching in the higher level function.
