“if”语句在使用数据驱动页时循环两次

Question

我有一个脚本，用于在导出数据驱动页面时将插入地图放置到特定页面上，该脚本是一个朋友的工作和我自己的一些来自其他项目的代码的合并。在

问题是代码将第15页和第16页导出了两次，一次是带插入地图的，另一次是没有的，我不知道为什么。在

我认为这与循环中的缩进有关，但我无法得到它，所以它以其他方式运行。任何帮助都将不胜感激！在

Answer 1

我相信你的问题是，当pgIndex为15时，它会按预期执行导出。然后检查pgIndex是否为16。pgIndex不是16，因此它会落入else并在不使用插入映射的情况下重新导出。我建议将第二个if改为elif
