Saya mencari cara untuk mengekspor tabel ArcGIS (dibuat dengan alat Sampel ) ke file teks melalui ArcPy.
Saya dapat melakukan ini di ArcGIS melalui menu konteks dengan mengklik kanan tabel, tetapi belum menemukan cara untuk skrip ini.

Jawaban:
Anda dapat melakukan ini menggunakan kursor untuk mengambil data dari tabel Anda dan menulis ke file teks yang dibatasi koma.
EDIT: Saya menambahkan blok kode yang lebih ringkas untuk menyelesaikan tugas menggunakan csv
modul Python
Jawaban Baru menggunakan kursor arcpy.da:
import arcpy,csv
table =r'c:\path\to\table'
outfile = r'c:\path\to\output\ascii\text\file'
#--first lets make a list of all of the fields in the table
fields = arcpy.ListFields(table)
field_names = [field.name for field in fields]
with open(outfile,'wb') as f:
dw = csv.DictWriter(f,field_names)
#--write all field names to the output file
dw.writeheader()
#--now we make the search cursor that will iterate through the rows of the table
with arcpy.da.SearchCursor(table,field_names) as cursor:
for row in cursor:
dw.writerow(dict(zip(field_names,row)))

Ini adalah sepotong kode yang saya gunakan. Ini membantu saya menghasilkan semua file output saya ke file .txt dengan kisaran dari 0,100. Semoga bermanfaat
for x in xrange(0,100):
if os.path.isfile(outfolder + "/" + "outputs" + str(x) +".shp" ):
