How to Extract values from a field and write them to a text file using Python?

Hi all,

I am using ArcGIS 10.0 Python 2.6. I need to get the values from a single field (APN) out of a PARCEL feature class attribute table and write them to a text file. The feature class contains about 20 different fields. I only need to write the values from APN.

The only info I can find is outdated. Can anyone help?

Thanks,
Christi Nelson
