Python实现读取目录所有文件的文件名并保存到txt文件代码

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

defTest():
 dir="J:\\1"
 outfile="binaries.txt"
 wildcard=".txt.exe.dll.lib"
 
 file=open(outfile,"w")
 ifnotfile:
   print("cannotopenthefile%sforwriting"%outfile)

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

Test()
