arcpy 零碎知识

记忆力越来越差，在这里记些东西：

1.使用 CURRENT 引用 ArcMap 中当前加载的地图文档时，有时需要刷新内容列表或活动视图（数据视图或布局视图）。

在 Python 窗口中输入以下两行，在每行后面按 ENTER：

>>> arcpy.RefreshTOC()
>>> arcpy.RefreshActiveView()

 2.遍历文件夹时，检索文件，判断是否为文件：s.path.isfile(fullpath)

import arcpy, os
folderPath = r"C:Project"
for filename in os.listdir(folderPath):
    fullpath = os.path.join(folderPath, filename)
    if os.path.isfile(fullpath):
        basename, extension = os.path.splitext(fullpath)
        if extension.lower() == ".mxd":
            mxd = arcpy.mapping.MapDocument(fullpath)
            mxd.findAndReplaceWorkspacePaths(r"C:ProjectData", r"\ComputerNameProjectData")
            mxd.save()
del mxd
