遍历目录的。

import os

def print_dir(arg, dirname, names):
print dirname
for n in names:
print os.path.join(dirname, n)

os.path.walk('.', print_dir, ())

[iambic]

import os

def print_dir(arg, dirname, names):
>>>print dirname
>>>>>>for n in names:
>>>>>>>>>print os.path.join(dirname, n)

os.path.walk('.', print_dir, ())
