By default the print statement sends to stdout
I want to send to stderr
Try
print "my meeage", file=sys.stderr
I got
SyntaxError: invalid syntax
I try
print "my message", sys.stderr
But it still sent to stdout.
What is the syntax?
I wouldn't understand Python's manual
print([object, ...][, sep=' '][, end='n'][, file=sys.stdout])¶
Print object(s) to the stream file, separated by sep and followed by end. sep, end and file, if present, must be given as keyword arguments.
All non-keyword arguments are converted to strings like str() does and written to the stream, separated by sep and followed by end. Both sep and end must be strings; they can also be None, which means to use the default values. If no object is given, print() will just write end.
The file argument must be an object with a write(string) method; if it is not present or None, sys.stdout will be used.

<snip quote from the manual>
That's only in Python 3 (or 2.6 with the proper __future__ import).
Before that, print is a statement. You'd do it like this:
print >sys.stderr, "whatever"
You should look at
<http://docs.python.org/reference/simple_stmts.ht ml#the-print-statement>,
not Python 3's documentation.

Why can't we have an additional 'print' statement, that behaves
exactly like 'print' but doesn't insert that damn blank between two
arguments?
Could be called 'printn' or 'prin1' or 'prinn' anything similar you
like.
Would make my life so much easier. Often I start with a nice and short
print statement, then there happen to be more arguments and neat
formatting becomes more important and as a result I find myself

Hi there,
First I'll apologise for my ignorance!
I have been attempting to compile some code that I found on the net.
AFAICT it's intended to be portable code (it was available as source and
as a DOS binary, but mention was made of UNIX in the readme - I am
compiling under Mac OS X, fwiw).

Hi,
I found print much more flexible that write method. Can I use print instead

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
