Ah yes, that was the sort of thing I was thinking of.

I am on 2.3.5 so I can do sum([x for y in foo for x in y])
So now looking at both your and Karl's ways, how do I catch
exceptions. My current (working) code looks like this:
def fleetHealth(self):
"""Iterate through each square to see if the whole fleet has been sunk."""
s = 0
for c in self.ranks:
for b in c:
try:
s += b.contents.size()
except:
pass
return s
I guess this could be significantly refactored! But... readability counts!
S.
