【问题描述】：
我是 python 脚本的新手，但一直在尝试监督一个前同事创建的脚本，以帮助我们在我的办公室自动化地图制作。我们最近从 ArcGIS 10.0 切换到 10.3，从 Python 2.6 切换到 Python 2.7。现在一些脚本不再工作。有没有人有任何提示可以帮助我开始了解导致此问题的可能原因？提前谢谢！
更新：不起作用的脚本不会产生错误。它只是达到 100%，但从未完成。似乎 100% 实际上并不是 100%，因为它停在“确定区域的最佳规模......”的位置。

【问题讨论】：

您可以从提供 CMVE 开始（即与 2.6 一起使用但在 2.7 中失败的最小可能脚本，更重要的是，什么不起作用，因为您希望它返回一组点你得到 [] 或一个例外）。我的猜测是 ArcGIS API 的变化不仅仅是 python 2.6 vs 2.7 的东西。

谢谢你，Foon。我在上面添加了更多细节。这有帮助吗？

不幸的是，正如我从经验中所知道的那样乏味和令人沮丧，解决这种升级不兼容问题的最佳方法之一是在每一行脚本之后包含
AddMessage。您知道它在您的第一行之后的某个地方，但在“将新结果设置为数据驱动页面索引...”之前（因为您没有看到），并且脚本中没有什么明显的地方我可以看到哪个会破坏在 10.3 中。除非他们已经淘汰UpdateCursor以支持da.UpdateCursor？
