Hi,
I just wrote a short test for indexing into structured arrays with
strings and found this:
In [4]: a = np.zeros((1,), dtype=[('f1', 'i4')])
In [5]: a['f1']
Out[5]: array([0])
In [6]: a['f2'] # not present -> error
---------------------------------------------------------------------------
ValueError Traceback (most recent call last)
/Users/mb312/<ipython console> in <module>()
ValueError: field named f2 not found.
In [7]: a[0]['f1'] # OK
Out[7]: 0
In [8]: a[0]['f2']
---------------------------------------------------------------------------
IndexError Traceback (most recent call last)
/Users/mb312/<ipython console> in <module>()
IndexError: invalid index
It seems odd to raise an 'IndexError' without a message about the
field name in the second case, and a ValueError with a good message in
the first.
Do y'all agree?
Matthew
