Python实现读取目录所有文件的文件名并保存到txt文件代码

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()
