Python: Current directory in an os.walk
<p>I need to get the current directory in an os.walk process. It works when there is just one subdirectory level but fails when there's more. Please advise...</p>

<p>[CODE]</p>

<pre><code># AFFECTS everything reachable from the directory named in "top",
# assuming there are no symbolic links.
# CAUTION:  This is dangerous!  For example, if top == '/', it
# could affect all your disk files.

import os, glob, arcpy, csv, sys, shutil, datetime
top = r'L:\Raster_Data\Topographic_Maps'
RootOutput = r'L:\Raster_Data\Topographic_Maps'
#FileList = csv.reader(open('FileList.csv'))
SearchString=['Temp_Pol', 'Spatial_Ex']

filecount=0
successcount=0
errorcount=0

print "Working in: "+os.getcwd()

list =[]
f = open(RootOutput+'\\Success_LOG.txt', 'a')
f.write("Log of files Succesfully processed. RESULT of process run @:"+str(datetime.datetime.now())+"\n")
f.close()

#for File in FileList:
for root, dirs, files in os.walk(top, topdown=False):
  #for directory in dirs:
    for file in files:
      #currentPath=os.path.join(root,directory)
      currentPath=os.path.abspath(file)
      os.chdir(currentPath)
      #arcpy.env.workspace = currentPath
      #print os.getcwd()
      lstFCs = glob.glob('*'+SearchString[0]+'*.shp')
      #print lstFCs
      OutPutDir=os.path.abspath(currentPath)
      for fc in lstFCs:
          filecount=filecount+1
          list.append(OutPutDir+"\\"+fc)       

      lstFCs = glob.glob('*'+SearchString[1]+'*.shp')
      #print lstFCs
      for fc in lstFCs:
          OutPutDir=RootOutput+"\\"+directory
          filecount=filecount+1
          list.append(OutPutDir+"\\"+fc)

print 'Merging: ' + str(list)
#arcpy.Merge_management(list, RootOutput+"\\Full_Extent.shp")
print 'Created: '+RootOutput+"\\Full_Extent.shp"
f = open(RootOutput+'\\Success_LOG.txt', 'a')
f.write(str(list)+"\n\n Merged to: "+RootOutput+"\\Full_Extent.shp")
f.close()
</code></pre>

<p>so the list should be appended with the fc and the full path to it but just gets the root path and the final part of the path -not the directories in between.</p>

<p>Thanks for your advise,</p>
