I still am not able to make my mock-up custom python class work as I
would like with asarray (though it works with "list"). What am I
missing? The way I read it this appears to be in support of extension
code that wants to expose the array interface, but I have a python
object that acts like a sequence (am I missing some important method)
that wants to work properly with numpy.asarray
class C:
def __init__(self):
self._data = (1,2,3,4,5)
def __iter__(self):
for i in self._data:
yield i
return
def __getitem__(self, i):
return self._data[i]
def __getslice__(self, i, j):
return self._data[i:j]
def __len__(self):
return len(self._data)
def __array_interface__(self):
return dict(
shape=(len(self._data),),
typestr='f',
version=3)
import numpy
c = C()
print numpy.asarray(c)
#for i in c:
# print i
