Python help for default value in attribute field

[CurtHale]

I would classify myself as a beginner at best using Arcmap.  I currently have an attribute table and feature class called WaterMeter and a field in that attribute table called City_Mater.  The field properties are text and a 50 character limit.  I have tried running python to assign a default field value for all of the individual features for the field City_Mater field so that the default value is Copper.  I have tried to run it several different ways in the python tool but with no success.  Could someone provide me with some insight?  Thanks

Hi,

You can assign a default value in the fields tab of the feature class, right-click properties on the FC in catalogues or catalog window.

If you need this done in python can you screenshot your inputs to the assign default to field method?

If more people would set appropriate defaults, it would solve lots of problems
