代碼： (使用os.listdir)

代碼如下:
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()

代碼：(使用os.walk) walk遞歸地對目錄及子目錄處理，每次返回的三項分別為：當(dāng)前遞歸的目錄，當(dāng)前遞歸的目錄下的所有子目錄，當(dāng)前遞歸的目錄下的所有文件。

代碼如下:
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()
