What's the use of the else in try/except/else?

[kj]

I know about the construct:

try:
    # do something 
except ...:
    # handle exception
else:
    # do something else

...but I can't come with an example in which the same couldn't be
accomplished with

try:
    # do something
    # do something else
except ...:
    # handle exception

The only significant difference I can come up with is that in the
second form, the except clause may be masking some unexpected
exceptions from the "do something else" part.  Is this the rationale
behind this else clause?  Or is there something more to it?

TIA!
