Yes, it's not in the Tutorial. But you must have found out about its existence somewhere ... 2.x manuals? > John pointed out its in Guido's "What's New in Python3.0" > Indeed its mentioned in PEP 3111, near end of What's New > and somewhat obscurely.

If you are sticking to 3.0, then you're not in the target audience for "What's New in Python3.0". Just read the docs on the input function: http://docs.python.org/3.0/library/functions.html#input or use help() at the interactive prompt: Python 3.0 (r30:67507, Dec 3 2008, 20:14:27) [MSC v.1500 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> help(input) Help on built-in function input in module builtins: input(...) input([prompt]) -> string Read a string from standard input.
