Also explain the logic in plain words. Else, we can only guess.

This will also help you and check the design.

Were the comments not enough? You keep taking turns until you get home
or die. Each turn has 4 phases.

while playing:
#phase 1 - fly every turn, you might die
#phase 2 - stuff shoots at you every turn, you might die
#phase 3 - may or may not get an event card, with certain cards you might 
die
#phase 4 - you drop bombs if you're over a target, you can't die here
game over, print score

 phases.

 #phase 1 - fly every turn, you might die
 #phase 2 - stuff shoots at you every turn, you might die
 #phase 3 - may or may not get an event card, with certain cards you might

 #phase 4 - you drop bombs if you're over a target, you can't die here
 game over, print score

Thinking about this this morning, I struck upon this idea, which seems
much cleaner:

--
def phase1():
   #do stuff
   return boolSurvived

def phase2():
   #do stuff
   return boolSurvived

def phase2():
   #do stuff
   return boolSurvived

def phase4():
   #do stuff

while playing:
#phase 1 - fly every turn, you might die
playing = phase1()

#phase 2 - stuff shoots at you every turn, you might die
if playing:
playing=phase2()

#phase 3 - may or may not get an event card, with certain cards you might 
die
if playing:
playing=phase3()

#phase 4 - you drop bombs if you're over a target, you can't die here
if playing:
phase4()

game over, print score

[Tutor] Better flow for this?

[R. Alan Monroe]

I started on an implementation of a solitaire board game simulating a
B52 bombing run ( http://victorypointgames.com/details.php?prodId=119
). It seems like there ought to be a better way to structure this
program flow, but it's escaping me at the moment.

(pseudo code)
-
playing=True
while playing:
#phase 1 - fly every turn, you might die
if dead:
playing=false
break
if you make it home intact:
playing=false
break
#phase 2 - stuff shoots at you every turn, you might die
if playing:
try:
for each thing that shoots at you:
if dead:
raise deaderror #this in particular seems horrible
except deaderror: #since you can't nest breaks
   playing=false
   break
#phase 3 - may or may not get an event card, with certain cards you might 
die
if playing:
#stuff
if dead:
playing=false
break
#phase 4 - you drop bombs if you're over a target, you can't die here
game over, print score

You don;t need if playing since the false conditions both break.
So you don;t need the try either...



 for each thing that shoots at you:
 if dead:
 raise deaderror #this in particular seems horrible
 except deaderror: #since you can't nest breaks
playing=false
break


And you don;t need the error, just make playing false and break



 #phase 3 - may or may not get an event card, with certain cards you might 
die
 if playing:
 #stuff


Again no need to check playing, you keep breaking...


 if dead:
 playing=false
 break


Not sure if you need this or not...



 #phase 4 - you drop bombs if you're over a target, you can't die here
game over, print score
