Re: [Numpy-discussion] recarray to csv

Excerpts from Guillaume Chérel's message of Fri Sep 03 09:32:02 -0400 2010:

Hello,

I'd like to know if there is a convenient routine to write recarrays into cvs files, with the first line of the file being the name of the fields.

Thanks, Guillaume

Yes, you can do this with the recfile package: http://pypi.python.org/pypi/recfile/0.40 http://code.google.com/p/recfile/ import numpy import recfile rec = numpy.zeros(3, dtype=[('x','f4'),('y','i8')]) rec['x'] = [0,1,2] rec['y'] = [0,1,2] recf = recfile.Open('filename.csv', 'w', delim=',') names = rec.dtype.names header = ','.join(names) recf.fobj.write(header+'\n') recf.write(rec) recf.close() Erin Scott Sheldon Brookhaven National Laboratory
