You can also use the "else" clause if there is stuff you want to run if the try

you don't intend to exit from the exception.
I admit that I've never really found a use for else in a try block.
I don;t see much advantage in
try: f(x)
except MyError:
pass
else:
g(x)
h(x)
over
try: f(x)
except MyError:
pass
g(x)
h(x)
Unless you really only want g(x) executed if there
is no MyError exception but want h(x) executed regardless.
I guess where h() is not using x it might be helpful but in most(all?)
of my code I've usually bailed when x has gone
wrong or I've fixed things such that hg() and h() are required.
I'm curious, how often do others use the try/else combination?
