Problem p03276 (python)

Fixed submission:

candls=list(map(int,input().split()))

distance_dict=[[x,abs(x)] for x in candls]

for x in range(0,N):
  if candls[x]>=0:
    x-=1
    break

resultlist=[]
minus=x
if K==1:
  print (min(abs(candls[minus]),abs(candls[minus+1])))
  exit()
elif minus==-1:
  print(abs(candls[K-1]))
  exit()
elif minus-K+1>=0:
  resultlist.append(abs(candls[minus-K+1]))
  for i in range(1,2*K):
    try:
      resultlist.append(abs(candls[minus+i])+abs(candls[minus-K+1+i])+min(candls[minus+i],abs(candls[minus-K+1+i])))
