More immediately, note that you are building a list of len(IN) ints every
time through the inner loop. A quick hit might be this simple change:
indexes = range(len(IN))
for i in indexes: #scan all elements of the list IN
for j in indexes:
if i != j:
if (IN[i].coordinates[0] == IN[j].coordinates[0] and
IN[i].coordinates[1] == IN[j].coordinates[1]):
SN.append(IN[i].label)
