Hi. I've been working in Python a bit, and got this error about what I was working converting to a scalar index. It keeps giving me a TypeError that only integer scalar arrays can be converted to the type of index I want. Can someone help make this work for me? I've been stuck on this for awhile.

A simple case that generates this error message:

In [8]: [1,2,3,4,5][np.array([1])]
TypeError                                 Traceback (most recent call last)
<ipython-input-8-55def8e1923d> in <module>()
----> 1 [1,2,3,4,5][np.array([1])]
TypeError: only integer scalar arrays can be converted to a scalar index

Some variations that work:

In [9]: [1,2,3,4,5][np.array(1)]     # this is a 0d array index
Out[9]: 2
In [10]: [1,2,3,4,5][np.array([1]).item()]    
Out[10]: 2
In [11]: np.array([1,2,3,4,5])[np.array([1])]
Out[11]: array([2])

Basic python list indexing is more restrictive than numpy's:

In [12]: [1,2,3,4,5][[1]]
TypeError: list indices must be integers or slices, not list
