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.
