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。

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。
