Section "3.1.2. Strings" says "*Once again*, the print() function produces the more readable output.", but as far as I can see (or grep), this is the first time that this aspect of print() is mentioned.
The sentence should be deleted. Print is *not* used in any of the previous examples. This is the first mention of print() in the chapter and is nonsensical in context.
Fixed in r86310. print was used in some examples following its mention, so a simple introduction to it was okay. It is introduced properly further down in the tutorial.
