Adding new field and populating with shapefile name

Question

I have a set of shapefiles that need a new field adding to them called "Policy_Ref". I then need to update this field with the shapefile name. However when I do, it uses the full title, including the .shp. However I do not want the .shp in the fields. This is my code so far:

import arcpy
arcpy.workspace.env = r"teamGIS/shp"
fcs = arcpy.ListFeatureClasses()
for fc in fcs:
 arcpy.AddField_management(fc, "Policy_Ref", "TEXT")
 arcpy.CalculateField_management(fc, "Policy_Ref", "'" + fc + "'")
 arcpy.Merge_management(fcs, "new_shp")

How do I remove the .shp either before or after the code is executed?

Answer 1

Or you could use a describe and .baseName

 fcs = arcpy.ListFeatureClasses("","","")
 for fc in fcs:
 desc = arcpy.Describe(fc)
 print fc
 print desc.baseName
 ActualName = desc.baseName

Answer 2

This is really a Python rather than ArcPy question, so would be best researched at Stack Overflow.

However, you can try changing:

arcpy.CalculateField_management(fc, "Policy_Ref", "'" + fc + "'")

to:

arcpy.CalculateField_management(fc, "Policy_Ref", "'" + fc.replace(".shp","") + "'")

• Michael Stimson: my personal favorite is fcName,fcExt = os.path.splitext(fc).. this way if there is no extension fcExt == '' but fcName always contains the name; this function also has tolerance for double extensions (eg. MyShp.tif.shp).
