Python advertises some basic service:
C:\Python24>python
Python 2.4.1 (#65, Mar 30 2005, 09:13:57) [MSC v.1310 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.

With numarray, help gives unhelpful responses:
import numarray.numarraycore as _n
c= _n.array((1, 2))
print 'rank Value:', c.rank
print 'c.rank Help:', help(c.rank)
Results:
rank Value: 1
c.rank Help:Help on int object:
class int(object)
| int(x[, base]) -> integer
|
| Convert a string or number to an integer, if possible. A floating
point
| argument will be truncated towards zero (this does not include a
................. etc etc.
Another example:
>>> help(c.copy)
<bound method NumArray.copy of array([1, 2])>
>>> help(c.copy)
Traceback (most recent call last):

>>>
c.copy.__doc_ does return the __doc__ string OK:
>>> c.copy.__doc__
'Returns a native byte order copy of the array.'
>>>
But c.rank.__doc__ does not:
>>> c.rank.__doc__
'int(x[, base]) -> integer\n\nConvert a string or number to an integer,
if possible. A floating point\nargument will be truncated towards zero
(this does not include a string\nrepresentation of a floating point
number!) When converting a string, use\nthe optional base. It is an
error to supply a base when converting a\nnon-string. If the argument is
outside the integer range a long object\nwill be returned instead.'
