python - Unpacking tuples/arrays/lists as indices for Numpy Arrays

Question

I would love to be able to do

>>> A = numpy.array(((1,2),(3,4)))
>>> idx = (0,0)
>>> A[*idx]

and get

1

however this is not valid syntax. Is there a way of doing this without explicitly writing out

>>> A[idx[0], idx[1]]

?

EDIT: Thanks for the replies. In my program I was indexing with a Numpy array rather than a tuple and getting strange results. Converting to a tuple as Alok suggests does the trick.

Answer 1

It's easier than you think:

>>> import numpy
>>> A = numpy.array(((1,2),(3,4)))
>>> idx = (0,0)
>>> A[idx]
1
