Arcpy批量合并多个gdb中相同的要素类

Arcpy批量合并多个gdb中相同的要素类，流程为：

1、将所有的gdb放在一个目录下，即代码中的inpath (path_allgdb_except_one)

2、剪切一个gdb作为合并后的输出gdb，即代码中的outgdb (one.gdb)

3、执行下面脚本 (arcgis10.3成功)

# -*- coding: cp936 -*- #
import os
import sys
import arcpy
inpath = r"D:\path_allgdb_except_one"
outgdb = r"D:\one.gdb"

arcpy.env.workspace = inpath
# list all file geodatabases in the current workspace
workspaces = arcpy.ListWorkspaces("*", "FileGDB")
for j, workspace in enumerate(workspaces):
    print('processing: ' + workspace)
    arcpy.env.workspace = workspace
    featureclasses = arcpy.ListFeatureClasses()
    for i, fc in enumerate(featureclasses):
        # print('     ' + fc)
        output = os.path.join(outgdb, os.path.splitext(fc)[0])
        # print output
        arcpy.Append_management(fc, output)
