Remove the wrong positives afterwards:
start = nomefile.find("XX")
while start != -1:
if nomefile[start:start+4] == "XXXX":
start += 4
else:
print "XX found at location", start
start += 3
start = nomefile.find("XX", start)
By the way, what do you want to do if there are runs of "X" with repeats
other than 2 or 4?
