[Numpy-discussion] Recarray attributes writeable (original) (raw)

Hi everyone -

Recarrays have convenience attributes such that fields may be accessed through "." in additioin to the "field()" method. These attributes are designed for read only; one cannot alter the data through them. Yet they are writeable:

tr=numpy.recarray(10, formats='i4,f8,f8', names='id,ra,dec') tr.field('ra')[:] = 0.0 tr.ra array([ 0., 0., 0., 0., 0., 0., 0., 0., 0., 0.])

tr.ra = 3 tr.ra 3 tr.field('ra') array([ 0., 0., 0., 0., 0., 0., 0., 0., 0., 0.])

I feel this should raise an exception, just as with trying to write to the "size" attribute. Any thoughts?

Erin
