python - Adding a field to a structured numpy array (2)

Question

I know there was already a question about this topic (cleanest way to add a field to a structured numpy array), see

Adding a field to a structured numpy array

but I have a question about the answer given there ...

If you're using numpy 1.3, there's also numpy.lib.recfunctions.append_fields()

I still have numpy 1.3, but it doesn't recognise this function, and I also didn't find anything about it in the documentation of numpy. What happened with the function? Is there another function that can do the same?

Answer 1

http://projects.scipy.org/numpy/browser/branches/1.3.x/numpy/lib/recfunctions.py?rev=8229

did you import?

from numpy.lib import recfunctions

recfunctions.append_fields(*your_args)  # base, names, data, ...

Seems like everything is working:
