Please see this:
>>> help(f.writelines)
Help on built-in function writelines:
writelines(...)
writelines(sequence_of_strings) -> None. Write the strings to the file.
Note that newlines are not added. The sequence can be any iterable
object
producing strings. This is equivalent to calling write() for each
string.
so you'd want this:
f.writelines([x+os.linesep for x in strings])
or something similar.
Why ? Ask the originator of this function.
One explanation:
If you do this:
f1 = file('file1')
f2 = file('file2','w')
f2.writelines(f1.readlines())
f1.close() ; f2.close()
all is how it should be.
