print statements without ()

[petec]

I have been findiing sites that include examples that have print ststements that don't use (), they use "".
When I try to execute these examples they fail unless I wrap () around them. Then I think they are still not performing as the author intended.
These all have to do with html webpages that execute cgi files that execute python code.

In particular webpages with radio buttons. Here are some links to such examples:
First Example

Second Example

And there are more.

What am I missing?
