风景，因走过而美丽。命运，因努力而精彩。南国园内看夭红，溪畔临风血艳浓。如果回到年少时光，那间学堂，我愿依靠在你身旁，陪你欣赏古人的诗章，往后的夕阳。

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()
