这段代码中还是出现了字符串连接问题。你需要检查一下fcs和dss这两个变量的值是否为NoneType，如果是的话，你需要在字符串连接之前进行判断，避免出现这种错误。

以下是修改后的代码：

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

    # 判断fcs和dss是否为NoneType
    fcs = arcpy.ListFeatureClasses()
    if fcs is not None:
        fcs = fcs + arcpy.ListTables()
    else:
        fcs = []

    dss = arcpy.ListDatasets()
    if dss is None:
        dss = []

    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，在对fcs和dss进行赋值之后，加入了判断是否为NoneType的代码。如果是，则将其赋值为空列表。这样可以避免出现字符串连接问题。
