我正在寻找一种通过ArcPy将ArcGIS表（使用“示例”工具创建的表）导出到文本文件的方法。

我可以通过右键单击表通过上下文菜单在ArcGIS中执行此操作，但是还没有找到编写脚本的方法。

#1 楼

您可以使用游标从表中获取数据并将其写入以逗号分隔的文本文件中。

编辑：我添加了一个更简洁的代码块，以使用Python的csv模块

使用arcpy.da游标的新答案：

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)))


使用旧式游标的新答案：

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:
    w = csv.writer(f)
    #--write all field names to the output file
    w.writerow(field_names)

    #--now we make the search cursor that will iterate through the rows of the table
    for row in arcpy.SearchCursor(table):
        field_vals = [row.getValue(field.name) for field in fields]
        w.writerow(field_vals)
    del row


旧答案：

import arcpy

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)

i = 1
f = open(outfile,'w')
for field in fields:
    #--write all field names to the output file
    if i < len(fields):
        f.write('%s,' % field.name)
        i += 1
    else:
        f.write('%s\n' % field.name)

#--now we make the search cursor that will iterate through the rows of the table
rows = arcpy.SearchCursor(table)
for row in rows:
    i = 1
    for field in fields:
        if i < len(fields):
            f.write('%s,' % row.getValue(field.name))
            i += 1
        else:
            f.write('%s\n' % row.getValue(field.name))
del rows
f.close()

@Jason-谢谢，这非常有帮助。我是新手，所以我不敢评论您接受的答案。我认为使用arcpy.da游标的新答案中存在一个小错误。以arcpy.da.SearchCursor（table）作为光标：应该与arcpy.da.SearchCursor（table，field_names）作为光标：

@TylerG很好，我已经编辑了答案，以包括数据访问游标所需的字段列表。谢谢。

#2 楼

您可能需要巧妙地命名为arcpy.ExportXYv_stats的“将要素属性导出为ASCII” http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//005p0000003v000000 

import arcpy

feature = "path to feature here"
# fieldnames must be explicitly provided. Note that you will get additional fields based on the feature type (e.g., "XCoord" and "YCoord" for point features)
fieldnames = [X.name for X in arcpy.ListFields(feature)]
# delimiter options "SPACE", "COMMA", or "SEMI-COLON"
# header options "ADD_FIELD_NAMES" or "NO_FIELD_NAMES"
arcpy.ExportXYv_stats(feature, fieldnames, "SPACE", "path to outfile", "ADD_FIELD_NAMES")

+1侦探！由于必须指定字段名称，因此它可以交互方式工作，但在模型或脚本中效果不佳。

这是我使用的一段代码。它可以帮助我将所有输出文件生成为.txt文件，范围从0,100。希望对您有所帮助

for x in xrange(0,100):
    if os.path.isfile(outfolder + "/" + "outputs" + str(x) +".shp" ):
       inFeatures = "selected_features" + str(x) +".shp"
       export_ASCII = "ASCII " + str(x) +".txt"
       arcpy.ExportXYv_stats(inFeatures, ["Cur1_pr2","Cur3_pl1","slp1"],"SPACE", export_ASCII,"ADD_FIELD_NAMES")
