copyfield based on Cxxxx

ElaineKuo

System: Windows Vista and ArcGIS 9.3

Hello,

I have 100 shapefiles called geocXXXX.shp (geoc0782, geoc9838, and geoc6728 etc)

In each shapefile, there is a field call CXXXX (C0782, C9838, and C6728 etc).
The field property is string, length =6.

Now I would like to make a new field call CXXXXD (C0782D, C9838D, and C6728D etc).
The field property is long integer, length =9.

Please kindly advise how to modify the follow code and thank you.

I see this snippet in the code, but don't know what it is used for as it looks like you get the name from the os.path.split section:

    # Break out the name, no path or extension, using the describe object.     desc = gp.describe(fc)     featureName = desc.name 

I don't see anywhere else that you are using the desc or featureName variables.  If so, the describe is fairly heavy operation, especially within a for loop.

If it really isn't needed, would probably decrease your run time substatially if removed.

Nor do these lines look necessary:

#Validate the new feature class name for the output workspace.     OutFeatureClass = outWorkspace + os.sep + gp.ValidateTableName(fc,outWorkspace)      #get file name     fcName, fcExt = os.path.splitext(fc)         #Get a list of the fields in the featureclass     fields = gp.listFields(fc, "C*", "String")
