Question

我是python脚本新手，但一直试图监督前同事创建的脚本，以帮助我们在办公室中自动完成地图制作。我们最近从ArcGIS 10.0切换到10.3，从Python 2.6切换到Python 2.7。现在一些脚本不再有效。有没有人有任何提示可以帮助我开始解决这个问题的可能原因？提前谢谢！

更新：不起作用的脚本不会产生错误。它只是100％，但从未完成。似乎100％实际上不是100％，因为它停留在“确定最佳缩放比例......”我已经粘贴在（下面）脚本开始此时脚本停止工作。

感谢大家的投入。 CWebster和我发现 df.zoomToSelectedFeatures（）命令没有选择要放大的功能（上面脚本中的第15行）。由于未选择任何功能，因此脚本将无法继续运行。

为了解决这个问题，我们用 df.extent = lyr.getSelectedExtent（）替换了 df.zoomToSelectedFeatures（）命令行，现在脚本再次运行完成。 / p>

我们不确定问题是否与ArcGIS 10.3更新或Python 2.7更新有关，但如果其他人遇到类似问题，这些信息可能有所帮助。

作为从ArcGIS 10.0升级的一部分，从Python 2.6升级到2.7后，在ArcGIS 10.3中运行脚本时出现问题
