Is there supposed to be a way to do 
  for x in 1,2,3: print x, 

If so, it's appears to be not working.  Is it just not in this release?

If not,  I would think that leaving out the print statement (just
because there is a print function) would represent a major problem for
cross-platform books and training materials.   Just a thought.  

How would one achieve this capability in Python 3.0?  Was it the
intention to remove this capability?

Thank you.

Regards,

Rich

What's wrong with

py> for x in 1,2,3:print(x,end=" ")
...
1 2 3

Closing as invalid.

-------------------------
I'd like to suggest (for those of us just now focusing on Python 3.0) replacing the last 3 bullet points of the paragraph "Common Stumbling Blocks?" 
http://docs.python.org/dev/3.0/whatsnew/3.0.html

With the following simple reference:

"The print statement has been REMOVED and is replaced by a print() function. SEE PEP 3105." 

Rather than burying 3105 in the middle of "other language changes."  That would do a lot to clear it up.  

A) Especially I'd like to suggest getting rid of the quite cryptic: "You’ll be finding yourself typing print x a lot in interactive mode." I had no idea that was a *warning message - meaning "it won't work..." And 

B) The rather misleading - "Also, print and print (x, y)  behave differently without warning:"

They certainly do...   But not in the way explained. "print" now displays "<built-in function print>" since it's a function...    What they probably meant was print()? 

Where would I suggest (or make) these changes to What's New? Is there a Doc Wiki?

Thanks!

Regards,

Rich

A plain "print" only results in output of "<built-in function print>" in
interactive mode, as interactive mode will not only perform the action,
but also display the result. In a Python script, a plain "print" will
have no effect.

Guido, can you take a look at the proposed "what's new" changes?

OK, I've added a big section about print to the front of the "common
stumbling blocks section, with all the info about print together, and a
few examples to clarify the most common changes.  You can see the
changes in subversion; they'll be live on docs.python.org/dev/3.0/ in
half a day or less.
