Help: Merging several shape files from a geodatabase

ZiaAhmed — Tue, 16 Aug 2011 18:34:10 GMT

I am trying to merge several shape files (county) from a geodatabase to create a shapefile for a state. I tryed following script - but it is not working.I am using ArcGis 10. Help will be appreciated. Thanks
zia

# Script:

import arcpy, os
## Set the workspace
arcpy.env.workspace= "K:/COUNTY_MUKEY/test.gdb"

fcs = arcpy.ListFeatureClasses()

# Create the multi-value string for the Analysis Union tool
fcs.reset
# Get the first feature class name and set the string variable
fc = fcs.next()
inputs = fc
# Get the next name and start the loop
fc = fcs.next()
while fc: # While the fc name is not empty
    inputs = inputs + ";" + fc
    fc= fcs.next()
print inputs
    # Process: Merge...
try:
    arcpy.Merge_management(inputs,"K:/STATE_ MUKEY/REA.gdb/soilmu_in")
    print "finished"
except:
    print "error"
    print arcpy.GetMessage()
    del arcpy

# Error
Traceback (most recent call last):
File "K:\Script\Python_Script\merge_shape.py", line 12, in <module>
    fcs.reset
AttributeError: 'list' object has no attribute 'reset'

Doesn't ListFeatureClasses return a list? If so, then the statement

inputs = ';'.join(fcs)

is all you need to build the string.

Could you please tell me where I am going to add [ "inputs = ';'.join(fcs)"] in this
script. Thanks Zia

Following simplified script works well for mergeing all shape files from a file geodatabase.
Thanks a lot. Zia

import arcpy, os, sys
## Set the workspace
#
output_feature_class = "K:/STATE_ MUKEY/AREA.gdb/soilmu_in"
featureType = "POLY"
#
input_workspace="K:/COUNTY_MUKEY/IN.gdb"
arcpy.env.workspace= input_workspace
fcs = arcpy.ListFeatureClasses()
#
arcpy.Merge_management(fcs,output_feature_class, "soilmu_in")
#
print arcpy.GetMessages

Yep, what Zia did here works well. Thanks for sharing your code!
