Python遍历文件夹枚举所有文件类型

>>> import os

>>> def enumfiles(path, dest):

files = os.listdir(path)

for f in files:

subpath = path + '/' + f

if (os.path.isfile(subpath)):

dest.append(subpath)

elif (os.path.isdir(subpath)):

if (f[0] == '.'):

pass

else:

enumfiles(subpath, dest)

>>> files = []

>>> path = "D:\cocos2d-x-2.2.3"

>>> enumfiles(path, files)

>>> exts = {}

>>> for f in files:

l = len(f)

p = f.rfind('.')

s = f.rfind('/')

if (l>0 and p!=-1 and p>s):

ext = f[p:l]

exts[ext] = 0

>>> exts.keys()

项目中，有时候需要在SVN中忽略掉某些文件类型，上面的脚本可以轻松做到，使用了os库，递归和字典的键值唯一性。
