Stuck in a loop

P: n/a
I wrote a simple algorithm and it keeps getting stuck in a loop. I
guess I'm just to tired to figure it out:

compcount=[5,4,2,2]
suitrank=[0,0,0,0]

trump=2
l,lt=0,0
while l<4:
while lt<4:
if l==trump:
l+=1
if l>3:
break
if lt==trump:
lt+=1
if compcount[l]<compcount[lt]:
suitrank[l]+=1
lt+=1
l+=1

In case you're wondering, the point is to rank suits from highest to
lowest based on how few cards each suit has. I hope that's enough
information.

Inside the inner loop, lt never changes if lt != trump, so you get an
infinite loop the first time when lt == 0.

I think you may have misindented the last two lines.

The easiest way to figure out somethinglike this is to print your variables
from inside the loop to see things stick, or if there is a cycle.

| compcount=[5,4,2,2]
| suitrank=[0,0,0,0]
|
| trump=2
| l,lt=0,0
| while l<4:
| while lt<4:

print l, lt

| if l==trump:
| l+=1
| if l>3:
| break
| if lt==trump:
| lt+=1
| if compcount[l]<compcount[lt]:
| suitrank[l]+=1
| lt+=1
| l+=1
