When I use numpy.__doc__ in IDLE under Win XP, I get a heap of words

Is there a way to get this formated properly.
help(object)
If I use dir(numpy), I get yet a very long list that starts as:
['ALLOW_THREADS', 'BUFSIZE', 'CLIP', 'DataSource', 'ERR_CALL',
'ERR_DEFAULT', 'ERR_DEFAULT2', 'ERR_IGNORE', 'ERR_LOG', 'ERR_PRINT',
'ERR_RAISE', 'ERR_WARN', 'FLOATING_POINT_SUPPORT', 'FPE_DIVIDEBYZERO',
'FPE_INVALID', 'FPE_OVERFLOW', 'FPE_UNDERFLOW', 'False_', 'Inf',
'Infinity', 'MAXDIMS', 'MachAr', 'NAN', 'NINF', 'NZERO', 'NaN',
'PINF', 'PZERO', 'PackageLoader', 'RAISE', 'RankWarning',
'SHIFT_DIVIDEBYZERO', 'SHIFT_INVALID', 'SHIFT_OVERFLOW',
'SHIFT_UNDERFLOW', 'ScalarType', 'Tester', 'True_',
'UFUNC_BUFSIZE_DEFAULT'
....
I see this might be a dictionary. What can I do to make it more
readable or useful, or is that it? Is there a more abc as in Linux?
You can use pprint module:
import pprint
pprint.pprint(dir(object))
though help() is usually better
It the IDLE shell, it's not possible to retrieve lines entered earlier
without copying them. Is there an edit facility?
Press Alt+P (Previous) and Alt+N (Next). Or you can click/select on the
line you want to copy and press Enter.
Add to this. Isn't there a way to see the arguments and descriptions of
functions?
Use help(). Or if you're doing this without human intervention, use
`inspect` module.
Wow, did I get a bad result. I hit Ctrl-P, I think instead of Alt-P, and
a little window came up showing it was about to print hundreds of pages.
I can canceled it, but too late. I turned off my printer quickly and
eventually stopped the onslaught.
I couldn't get Alt-P or N to work.
Another question. In interactive mode, how does one know what modules
are active? Is there a way to list them with a simple command?
