Michael,

This might help:

import os
path = [the path to the directory that contains all the sub-directories you want to work in]
for root, dirs, files in os.walk(path):
     for file in files:
          if file.split(".")[-1]==".mxd":
                [do something to it, or put it in a list for later use, etc...]
                [if you did 'print str(root)+os.sep+file' it will give you all the paths to the mxds and you could use that to do your arcpy.mapping stuff]
          else:
                pass

There could be another/better way to do it, but that should at least put you on the right path (pun intended) to find all the mxds in the sub-directories.

If you’re confident that all of the MXDs you want to address are in the form subdirectory/document.mxd, then the glob module should work to give you a list based on the string

path + "/*/*.mxd"

You could append this to

path + "/*.mxd"

to address all of the files of interest in one list.

Hi All,
I have been working with Python quite a bit more since the Spring NeArc meeting but I'm still pretty new to it and had a question. I'm wondering how I can get a script to run not only on files in a folder, but also files in subdirectories within that folder. The script I put together goes into each MXD in the folder I specifiy and re-sources one of our files that has been renamed. It works, but I have MXDs saved in subdirectories and it would be so much easier to have the script run on the main folder "MXDs" rather than have to specify a new subdirectory everytime I want to run it on a set of MXDs.
Is this possible? My research suggests a walk function [os.walk()] or using the glob module?
Here is the code I have been using. Feel free to give any feedback on it as I am still a rookie with Python:
import arcpy, os
path = r"I:/ARC/DATA/MXDs/Weekly Report"
for fileName in os.listdir(path):
    fullPath = os.path.join(path, fileName)
    if os.path.isfile(fullPath):
        basename, extension = os.path.splitext(fullPath)
        if extension == ".mxd":
            mxd = arcpy.mapping.MapDocument(fullPath)
            print "MXD: " + fullPath
            for df in arcpy.mapping.ListDataFrames(mxd):
                for lyr in arcpy.mapping.ListLayers(mxd,"",df):
                    findthis = 'Positive Trees'
                    findthat = 'Infested Trees'
                    if findthis in lyr.name or findthat in lyr.name:
                        lyr.replaceDataSource(r'I:/ARC/Data/InfestedTrees/Infested_trees.gdb','FILEGDB_WORKSPACE','Trees')
                        print(lyr.name + " - Layer Resourced to Infested Trees")
                    else:
                        pass
                arcpy.RefreshTOC()
                arcpy.RefreshActiveView()
                mxd.save()
print "--Script complete--"


Thanks!
