In ruby, the equivalent to try...except is begin...rescue. In the
rescue section you can ask it to retry the begin section. So, for
example:

b=0
begin
  puts 1/b
rescue
  b=1
  retry # <- this little guy
end

I don't think python has any equivalent (could be wrong). You can do
something like this however:

b=0
def do_stuff():
  print 1/b
try:
  do_stuff()
except:
  b=1
  do_stuff()
