DictReader and fieldnames

[Ted To]

Is it possible to grab the fieldnames that the csv DictReader module
automatically reads from the first line of the input file?

Thanks,
Ted To

Ted Is it possible to grab the fieldnames that the csv DictReader
Ted module automatically reads from the first line of the input file?

Like this, perhaps?

 rdr = csv.DictReader(open(f.csv, rb))
 rdr.fieldnames
['col1', 'col2', 'color']
 rdr.next()
{'color': '3', 'col2': '2', 'col1': '1'}

Ted Thanks.  Is there any way to make this work before actually reading
Ted in a row of data?  In version 2.5, I need to first do a rdr.next()
Ted before rdr.fieldnames gives me anything.

If you know the csv file contains column headers this should work:

f = open(f.csv, rb)
names = csv.reader(f).next()
rdr = csv.DictReader(f, fieldnames=names)
