help() function screen output
Using python 3.4 32 bit on windows 7 64 bit machine, and when, for example, type in something like the following in interpreter window: help(str) It will populate the screen with one full screen of information, with a prompt of --more-- to hit enter, or something to continue displaying information, but, when, for example, hit enter key, it merely populates one more line of info, each time - under pythn 2.7, it seemed to render one full screen of info each time. Is there rather a different keystroke should use to invoke that, or is this a python 3.4 feature/issue?

Are you sure? I don't have Windows to try, but in Linux using both Python 2.7 and 3.3, pressing Enter advances by a single line. Is there rather a different keystroke should use to invoke that, or is this a python 3.4 feature/issue? Try using the Space key to advance an entire page. You can also try Page Up and Page Down keys. The exact keys will depend on the pager program used by help. The help function depends on the pydoc module, which tries to use your operating system's pager program for displaying pages of text. On Linux, that may be the external programs more or less. I don't know what Windows uses. If there is no external pager program available, pydoc may end up using its own internal pager. So the exact keys used will differ. -- Steven -- https://mail.python.org/mailman/listinfo/python-list

- Original Message - Specifically, the last two lines show: space Display next page ret Display next line which is, I suspect, what you're after here. (If you're interested, the code for all this is in the pydoc module (Lib\pydoc.py) in the getpager() function. TJG -- https://mail.python.org/mailman/listinfo/python-list Yes, that makes sense/works - wonder what changed recently in my overall configuration/setup - suppose might have something to do with screen reader's system wide interference - maybe it was passing a different effective keystroke through to command line prompt before, or something, since am 99.9% sure always just used ret key to advance one screen at a time before - who knows, but, main thing is, yes, space bar does what I want it to.

You can also try Page Up and Page Down keys. Nada In Idle Shell, help displays entire text and one can scroll up and down as desired with scrollbar or PageUp/Down or arrows. -- Terry Jan Reedy -- https://mail.python.org/mailman/listinfo/python-list

There's some hand-waving going on there because it can/will be overridden if you have a different more executable available before the system-provided more.com or if you have a PAGER env var set. If you, at the Windows command prompt (ie *not* in Python), type: more /? You can see the various keystrokes which the program responds to. Specifically, the last two lines show: space Display next page ret Display next line which is, I suspect, what you're after here.

Ok, strangely, while am relatively sure 2.7 rendered a screen at a time before when hitting enter key, it now also seems to advance one line at a time, but, yes, seems like space bar does advance a whole screen in both versions, and page up/down doesn't react, but, space bar will do for now...smile And, I generally let it render a screen full, and then review the screen contents using screen-reader screen review functionality, but, in this case it pretty much matches what people see.
