You're correct;  the best way to suppress the newline at the end of
print is to use the trailing comma.  But since print is for lines, it
usually is a good default.  If you don't want to get any extra
characters, just use write().  It takes a string, and outputs exactly
what it's given.

I assumed you were complaining about the conversion of newline to
carriage-return-newline, which is done by default on Windows, and can be
suppressed by opening the file with "b" as the mode parameter.
