I am a python newbie and have obtained a script that lets the user input a directory where shapefiles are located (ex., c:\programfiles\shapefiles). It then creates a field within each shapefile and adds the directory path that was input and the shapefile name (ex., c:\programfiles\shapefiles\name.shp). I would like to populate the field with just the directory name (ex., shapefiles). I know there is a command that will split the directory name, but how do I return the basename as a function ? Thanks in advance.
import sys, string, os, arcgisscripting
gp = arcgisscripting.create()
# this is the directory user must specify
gp.workspace = sys.argv[1]
# declare the given workspace so we can use it in the update field process
direct = gp.workspace
try:
fcs = gp.ListFeatureClasses("*", "all")
fcs.reset()
fc = fcs.Next()
while fc:
fields = gp.ListFields(fc, "Airport")
field_found = fields.Next()
# check if the field allready exist.
if field_found:
gp.AddMessage("Field %s found in %s and i am going to delete it" % ("Airport", fc))
# delete the "SHP_DIR" field
gp.DeleteField_management(fc, "Airport")
gp.AddMessage("Field %s deleted from %s" % ("Airport", fc))
# add it back
gp.AddField_management (fc, "Airport", "text", "", "", "50")
gp.AddMessage("Field %s added to %s" % ("Airport", fc))
# calculate the field passing the directory and the filename
gp.CalculateField_management (fc, "Airport", '"' + direct + '\\' + fc + '"')
fc = fcs.Next()
else:
gp.addMessage(" layer %s has been found and there is no Airport" % (fc))
# Create the new field
gp.AddField_management (fc, "Airport", "text", "", "", "50")
gp.AddMessage("Field %s added to %s" % ("Airport", fc))
# Apply the directory and filename to all entries
gp.CalculateField_management (fc, "Airport", '"' + direct + '\\' + fc + '"')
fc = fcs.Next()
gp.AddMessage("field has been added successfully")
# Remove directory

gp.AddMessage(mes)
