edit = arcpy.da.Editor(arcpy.env.workspace)

这段代码使用了ArcPy库中的`arcpy.da.Editor`类来创建一个编辑器对象,用于管理数据的编辑操作。根据你提供的代码,我注意到你正在尝试在`arcpy.env.workspace`中创建一个编辑器对象。
然而,根据你之前提到的"cannot open workspace"错误,可能是由于工作区路径错误或其他问题导致的。在使用`arcpy.da.Editor`之前,请确保你已经正确设置了工作区路径。
以下是一个示例,展示如何正确使用`arcpy.da.Editor`来创建编辑器对象并启动编辑会话:
```python
import arcpy
# 设置工作区路径
workspace = "path/to/your/workspace"
arcpy.env.workspace = workspace
# 创建编辑器对象
edit = arcpy.da.Editor(workspace)
# 启动编辑会话
edit.startEditing(False, True) # 第一个参数表示不保存版本,第二个参数表示启用多用户编辑
# 进行编辑操作
# ...
# 停止编辑会话
edit.stopEditing(True) # 参数表示保存所做的更改
```
请确保将"path/to/your/workspace"替换为你实际的工作区路径。同时,确保你在使用`arcpy.da.Editor`之前已经解决了无法打开工作区的问题。
如果你仍然遇到问题,请提供更多详细的错误信息和相关代码,我将尽力帮助你解决问题。

这里是修改后的代码,你可以尝试运行看看。
```python
import sys
import arcpy
import string
reload(sys)
sys.setdefaultencoding('utf-8')
try:
workspace = 'C:\Users\Administrator\Desktop\\qwe'
outdb = 'C:\Users\Administrator\Desktop\\lutian.mdb'
arcpy.env.workspace = workspace
files = arcpy.ListFiles('*.*db')
arcpy.env.workspace = outdb
fcs = arcpy.ListFeatureClasses()
fcs = fcs + arcpy.ListTables()
dss = arcpy.ListDatasets()
for File in files:
for fc in fcs:
arcpy.Append_management(workspace + '\\' + File + '\\' + fc, outdb + '\\' + fc)
for ds in dss:
fcs1 = arcpy.ListFeatureClasses(feature_dataset = ds)
for fc1 in fcs1:
arcpy.Append_management(workspace + '\\' + File + '\\' + ds + '\\' + fc1, outdb + '\\' + ds + '\\' + fc1)
except arcpy.ExecuteError:
print arcpy.GetMessages()
```
修改后的代码中,缩进问题已经被修复,每个代码块都正确缩进。另外,由于你使用了Python 2.x版本,所以在代码中加入了`reload(sys)`和`sys.setdefaultencoding('utf-8')`,以确保正确处理中文字符集。
>>> import sys ... import arcpy ... import string ... ... reload(sys) ... sys.setdefaultencoding('utf-8') ... ... try: ... workspace = 'C:\Users\Administrator\Desktop\\qwe' ... outdb = 'C:\Users\Administrator\Desktop\\lutian.mdb' ... arcpy.env.workspace = workspace ... files = arcpy.ListFiles('*.*db') ... arcpy.env.workspace = outdb ... fcs = arcpy.ListFeatureClasses() ... fcs = fcs + arcpy.ListTables() ... dss = arcpy.ListDatasets() ... ... for File in files: ... for fc in fcs: ... arcpy.Append_management(workspace + '\\' + File + '\\' + fc, outdb + '\\' + fc) ... ... for ds in dss: ... fcs1 = arcpy.ListFeatureClasses(feature_dataset = ds) ... for fc1 in fcs1: ... arcpy.Append_management(workspace + '\\' + File + '\\' + ds + '\\' + fc1, outdb + '\\' + ds + '\\' + fc1) ... ... except arcpy.ExecuteError: ... print arcpy.GetMessages() ... Runtime error Traceback (most recent call last): File "<string>", line 15, in <module> TypeError: unsupported operand type(s) for +: 'NoneType' and 'NoneType',根据错误完善此代码
这段代码中出现了两个问题,一个是缩进问题,一个是字符串连接问题。以下是修改后的代码。
```python
import sys
import arcpy
import string
reload(sys)
sys.setdefaultencoding('utf-8')
try:
workspace = 'C:\\Users\\Administrator\\Desktop\\qwe'
outdb = 'C:\\Users\\Administrator\\Desktop\\lutian.mdb'
arcpy.env.workspace = workspace
files = arcpy.ListFiles('*.*db')
arcpy.env.workspace = outdb
fcs = arcpy.ListFeatureClasses()
fcs = fcs + arcpy.ListTables()
dss = arcpy.ListDatasets()
for File in files:
for fc in fcs:
arcpy.Append_management(workspace + '\\' + File + '\\' + fc, outdb + '\\' + fc)
for ds in dss:
fcs1 = arcpy.ListFeatureClasses(feature_dataset = ds)
for fc1 in fcs1:
arcpy.Append_management(workspace + '\\' + File + '\\' + ds + '\\' + fc1, outdb + '\\' + ds + '\\' + fc1)
except arcpy.ExecuteError:
print(arcpy.GetMessages())
```
修改后的代码中,缩进问题已经被修复,并且修改了字符串连接方式,使用双反斜杠来转义路径中的反斜杠,防止出现字符串连接问题。另外,在except语句中,使用了print函数来输出错误信息。
