python实例31[列出目录下所有的文件到txt]

 

代码： (使用os.listdir) 

import  os

def  ListFilesToTxt(dir,file,wildcard,recursion):
    exts  =  wildcard.split( "   " )
    files  =  os.listdir(dir)
     for  name  in  files:
        fullname = os.path.join(dir,name)
         if (os.path.isdir(fullname)  &  recursion):
            ListFilesToTxt(fullname,file,wildcard,recursion)
         else :
             for  ext  in  exts:
                 if (name.endswith(ext)):
                    file.write(name  +   " \n " )
                     break

def  Test():
  dir = " J:\\1 "
  outfile = " binaries.txt "
  wildcard  =   " .txt .exe .dll .lib "
  
  file  =  open(outfile, " w " )
   if   not  file:
     print  ( " cannot open the file %s for writing "   %  outfile)

  ListFilesToTxt(dir,file,wildcard,  1 )
  
  file.close()

Test()

 

 

代码：(使用os.walk) walk递归地对目录及子目录处理，每次返回的三项分别为：当前递归的目录，当前递归的目录下的所有子目录，当前递归的目录下的所有文件

import  os

def  ListFilesToTxt(dir,file,wildcard,recursion):
    exts  =  wildcard.split( "   " )
     for  root, subdirs, files  in  os.walk(dir):
         for  name  in  files:
             for  ext  in  exts:
                 if (name.endswith(ext)):
                    file.write(name  +   " \n " )
                     break
         if ( not  recursion):
             break

def  Test():
  dir = " J:\\1 "
  outfile = " binaries.txt "
  wildcard  =   " .txt .exe .dll .lib "
  
  file  =  open(outfile, " w " )
   if   not  file:
     print  ( " cannot open the file %s for writing "   %  outfile)

  ListFilesToTxt(dir,file,wildcard, 0)
  
  file.close()

Test()
