Or more succintly (but not tested):
sections = [
("3", "section_1")
("5", "section_2")
("\xFF", "section_3")
]
with open(input_path) as input_file:
lines = iter(input_file)
for end, path in sections:
with open(path, "w") as output_file:
for line in lines:
if line >= end:
break
output_file.write(line)
