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?
