If your data doesn't contain any spaces that's fine. Otherwise you need a
way to distinguish between space as a delimiter and space inside a field, e.
g. by escaping it:
>>> w = csv.writer(sys.stdout, delimiter=" ", quoting=csv.QUOTE_NONE,
escapechar="\\")
>>> w.writerow(["a", "b c"])
a b\ c

In text mode Windows translates "\n" to b"\r\n" in the file. Python allows
you to override that:
>>> help(open)
Help on built-in function open in module io:
open(...)
open(file, mode='r', buffering=-1, encoding=None,
errors=None, newline=None, closefd=True, opener=None) -> file
object
<snip>
newline controls how universal newlines works (it only applies to text
mode). It can be None, '', '\n', '\r', and '\r\n'. It works as
follows:
<snip>
* On output, if newline is None, any '\n' characters written are
translated to the system default line separator, os.linesep. If
newline is '' or '\n', no translation takes place. If newline is any
of the other legal values, any '\n' characters written are translated
to the given string.
So you need to specify newlines:
with open(dest, "w", newline="") as outstream:
