Python:os.walk中的当前目录

Question

我需要在os.walk进程中获取当前目录.它只在一个子目录级别有效,但在有更多时失败.请指教...

# 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()

所以列表应该附加fc和它的完整路径,但只是获取根路径和路径的最后部分 - 而不是之间的目录.

感谢您的意见,

谢谢大家，我使用了论坛的输入来完成脚本。下面是给任何想要的人的。最好的，

# 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, arcpy, sys, datetime
top = os.getcwd()
RootOutput = top
FileTypes=['shp']
SearchStrings=['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 root, dirs, files in os.walk(top, topdown=False):
    for fl in files:
      currentFile=os.path.join(root, fl)
      for FileType in FileTypes:
          status= str.endswith(currentFile,FileType)
          if str(status) == 'True':
              for SearchString in SearchStrings:
                  if str(SearchString in currentFile) == 'True':
                    #print str(currentFile)+str(status)       
                    filecount=filecount+1
                    list.append(currentFile)

print 'Merging: ' + str(list)

#替换为您想要在生成的文件列表上执行的任何函数。#arcpy.Merge_management(列表, 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")
