[Numpy-discussion] casting homogeneous struct arrays

[Simon B. <si...@ar...>]

This is something I will need to be able do:

>>> a=numpy.array( [(1,2,3)], list('lll') )
>>> a.astype( 'l' )
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: an integer is required

(and what a strange error message).

Is there a workaround ?
.tostring/.fromstring incurs a memcopy copy, if i am not mistaken.

Simon.
