Debugging or Not Debugging

#1

I was working on USACO Shell Game and submitted a solution for python but it kept giving me an EOF error while I did it, however in my Python IDE it works perfectly fine. Is there a bug in my code that my IDE doesn’t recognize or is it correct?

actions = []
pebblepos = 0
allvaluesonpebblepos = []
points = 0
n = int(input())

for k in range(n):
    actions.append(list(input().split()))

pebblepos = 1

for k in range(len(actions)):
    if str(pebblepos) == actions[k][0]:
        pebblepos = actions[k][1]
    elif str(pebblepos) == actions[k][1]:
        pebblepos = actions[k][0]
    if actions[k][2] == str(pebblepos):
        points += 1
        
allvaluesonpebblepos.append(points)
points = 0
pebblepos = 2

for k in range(len(actions)):
    if str(pebblepos) == actions[k][0]:
        pebblepos = actions[k][1]
    elif str(pebblepos) == actions[k][1]:
        pebblepos = actions[k][0]
    if actions[k][2] == str(pebblepos):
        points += 1
        
allvaluesonpebblepos.append(points)
pebblepos = 3
points = 0

for k in range(len(actions)):
    if str(pebblepos) == actions[k][0]:
        pebblepos = actions[k][1]
    elif str(pebblepos) == actions[k][1]:
        pebblepos = actions[k][0]
    if actions[k][2] == str(pebblepos):
        points += 1

allvaluesonpebblepos.append(points)
print(max(allvaluesonpebblepos))

Never mind I solve the issue by using files instead of input output.
