import arcpy

workspace = r'D:\...\xxx.mdb'
arcpy.env.workspace = workspace
featureclasses = arcpy.ListFeatureClasses()
for fc in featureclasses:
    cur = arcpy.da.UpdateCursor(fc, ['SHAPE@AREA', 'ZDMJ', 'ZDDM'])
    for row in cur:
        try:
            mjRes = round(row[0] / 666.667, 2)
            row[1] = mjRes
            cur.updateRow(row)
        except:
            print(str(row[2]) + '---Error!')
    del cur
    print(fc + '---layer successful!')
