This approach is also viable in Python 2.6 and 2.7 if you use io.open()
instead of the builtin.
To limit memory consumption for big files you can replace
target.write(source.read())
with
shutil.copyfileobj(source, target)
If you want to be sure that line endings are preserved open both files with
io.open(..., newline="") # disable newline translation
