Since the lines that handle writing to the file aren't indented as far
as the line that splits the data, they are not part of the loop. They
are only executed once after the loop has completed, with town and
latlong set to the values they got at the last iteration of the loop.
It should look more like this:
for line in open("datafile.txt"):
town, latlong = line.split('\t')
f = open(town + ".txt", "w+")
f.write(HEADER + "\n")
f.write(SUBHEADER + ": " + town + "\n")
f.write("LAT/LONG" + ": " + latlong + "\n")
f.close()
