The os.write function can be used to writes bytes into a file descriptor (not file object). If I execute os.write(fd, \'\\n\'), o
os.write
os.write(fd, \'\\n\')
How about os.write(, os.linesep)? (import os is unnecessary because you seem to have already imported it, otherwise you'd be getting errors using os.write to begin with.)
os.write(, os.linesep)
import os
