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 _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
