If the data easily fits into memory just keep it in one list per section
header = [...]
body = [...]
footer = [...]
...
body.append("something more\n")
footer[:] = ["new footer\n"]
...
with open(filename, "w") as f:
for section in (header, body, footer):
f.writelines(section)
If the sections are not known in advance put them into a dictionary or a
list.
If you are free to choose the file format you may use
