I was trying to change the one-dim array into a two-dim array so I could easily retrieve columns. I now use a pandas DataFrame to do that.
Numpy can do that, if I understand what you want correctly, but it requires an unintuitive trick. The trick is to index the array with the name of a field, and *only* the name of the field. For example, the following gives you a slice containing all the values from the 'v02' fields of your data: array['v02'] Note: Indexing with a field name generally seems to follow a different set of rules. Some things that you'd think would work don't, e.g. array[:, 'v02'] fails with a rather confusing error message. Also, array[0, 'v02'] doesn't work either, and has to be written array[0]['v02'] instead. -- Greg -- https://mail.python.org/mailman/listinfo/python-list
