NoName, Asking people to download a zip file from a website written in
a language and character set that they probably are not familiar with
is liable to make them rather nervous and not bother. It's not a good
way to ask for help. All you had to do was display the file contents
unambiguously, like this:

C:\downloads>\python30\python
Python 3.0 (r30:67507, Dec  3 2008, 20:14:27) [MSC v.1500 32 bit
(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> open('11.py', 'rb').read()
b"# -*- coding: cp866 -*- \r\nprint('test')"
>>> ^Z

So, there's nothing very remarkable there ... a trailing space on the
end of the first line, the second line is not terminated by \r\n, no
non-ASCII characters in the file, ... nothing that might cause Python
to give you a syntax error.

... and it doesn't give a syntax error:

C:\downloads>\python30\python 11.py
test

If you still maintain that you are getting the syntax error mentioned
in your first posting, please construct a file that causes the error
to happen on your machine (what type of machine? what OS are you
using?) and show (like I did above) firstly what is in the file and
secondly what happens when you run it. No hex editors, no websites, no
zip files, just plain Python like I did.
