| 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=" ")" ------------------------- 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 "" 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!

| A plain "print" only results in output of "" 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. |
