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
