When using a while True loop you need ttto have an explicit break
statement somewhere to get out. Personally I like to keep that 
near the top of the loop if possible - just so that I can
find it easily!

So in your case I'd add a test like

if mo_hp >= 0:

right at the top of the loop.

If there were other statements after the loop these would then
get executed but since you don't your program will naturally 

Note that if you had an else clause in your while loop(quite unusual)
it does not get executed after a break - the only useful feature I've
found for a loop else condition!


while True:
else:  print 'never executed'
print 'exited'
