简单的方法:

list_output_files = [os.getcwd()+"\\"+f for f in os.listdir(os.getcwd())]

递归实现

import os

def scan_dir(dir):
    for name in os.listdir(dir):
        path = os.path.join(dir, name)
        if os.path.isfile(path):
            print path
        else:
            scan_dir(path)

只递归列出文件的漂亮的一行代码。我在setup.py package_data指令中使用了这个:

import os

[os.path.join(x[0],y) for x in os.walk('<some_directory>') for y in x[2]]

我知道这不是问题的答案，但可能会派上用场

供参考添加扩展或ext文件的过滤器 进口操作系统

path = '.'
for dirname, dirnames, filenames in os.walk(path):
    # print path to all filenames with extension py.
    for filename in filenames:
        fname_path = os.path.join(dirname, filename)
        fext = os.path.splitext(fname_path)[1]
        if fext == '.py':
            print fname_path
        else:
            continue

#import modules
import os

_CURRENT_DIR = '.'


def rec_tree_traverse(curr_dir, indent):
    "recurcive function to traverse the directory"
    #print "[traverse_tree]"

    try :
        dfList = [os.path.join(curr_dir, f_or_d) for f_or_d in os.listdir(curr_dir)]
    except:
        print "wrong path name/directory name"
        return

    for file_or_dir in dfList:

        if os.path.isdir(file_or_dir):
            #print "dir  : ",
            print indent, file_or_dir,"\\"
            rec_tree_traverse(file_or_dir, indent*2)

        if os.path.isfile(file_or_dir):
            #print "file : ",
            print indent, file_or_dir

    #end if for loop
#end of traverse_tree()

def main():

    base_dir = _CURRENT_DIR

    rec_tree_traverse(base_dir," ")

    raw_input("enter any key to exit....")
#end of main()


if __name__ == '__main__':
    main()

虽然os.listdir()用于生成文件和目录名称的列表很好，但一旦有了这些名称，通常您还想做更多的事情——在Python3中，pathlib使这些其他杂事变得简单。让我们看一看，看看你是否和我一样喜欢它。

要列出目录内容，构造一个Path对象并获取迭代器:

In [16]: Path('/etc').iterdir()
Out[16]: <generator object Path.iterdir at 0x110853fc0>

如果我们只想要一个事物名称的列表

In [17]: [x.name for x in Path('/etc').iterdir()]
Out[17]:
['emond.d',
 'ntp-restrict.conf',
 'periodic',

如果你只想要dirs:

In [18]: [x.name for x in Path('/etc').iterdir() if x.is_dir()]
Out[18]:
['emond.d',
 'periodic',
 'mach_init.d',

如果你想要该树中所有conf文件的名称:

In [20]: [x.name for x in Path('/etc').glob('**/*.conf')]
Out[20]:
['ntp-restrict.conf',
 'dnsextd.conf',
 'syslog.conf',

如果你想在树>= 1K中列出conf文件:

In [23]: [x.name for x in Path('/etc').glob('**/*.conf') if x.stat().st_size > 1024]
Out[23]:
['dnsextd.conf',
 'pf.conf',
 'autofs.conf',

解析相对路径变得简单:

In [32]: Path('../Operational Metrics.md').resolve()
Out[32]: PosixPath('/Users/starver/code/xxxx/Operational Metrics.md')

使用路径导航非常清楚(尽管出乎意料):

In [10]: p = Path('.')

In [11]: core = p / 'web' / 'core'

In [13]: [x for x in core.iterdir() if x.is_file()]
Out[13]:
[PosixPath('web/core/metrics.py'),
 PosixPath('web/core/services.py'),
 PosixPath('web/core/querysets.py'),
