a=strings.array(None, itemsize = 4, shape=1, kind=strings.RawCharArray) a[0] = '0\0\0\0' print repr(a >= '0\x00\x00\x00\x01') array([0], type=Bool)
You'll note that I "hand padded" the assigned value; because RawCharArray is a little used feature, it needs more work. I think RawCharArray either makes partial/inconsistent use of NULL padding.
Well, I've already tried that, but what I would like is to have the possibility to assign values *and* padding with NULL values. However, using a RawCharArray does not allow this:
a=strings.array(None, itemsize = 4, shape=1, kind=strings.RawCharArray) a RawCharArray([' ']) a[0] = str(0) Traceback (most recent call last): File "<stdin>", line 1, in ? File "/usr/local/lib/python2.4/site-packages/numarray/strings.py", line 185, in _setitem where[bo:bo+self._itemsize] = self.pad(value)[0:self._itemsize] TypeError: right operand length must match slice length
Give RawCharArray a try; it *is* the basis of CharArray, so it basically works but there will likely be a few issues to sort out. My guess is that anything that really needs fixing can be added for numarray-1.2.
Mmm, perhaps having the possibility to select the pad value in CharArray creation time would be nice. Cheers, -- Francesc Altet >qo< http://www.carabos.com/ Cárabos Coop. V. V V Enjoy Data ""
