下面是我经常使用的一个辅助函数:

import os

def listdir_fullpath(d):
    return [os.path.join(d, f) for f in os.listdir(d)]

你可以使用

os.listdir(path)

参考和更多的操作系统函数看这里:

Python 2文档:https://docs.python.org/2/library/os.html#os.listdir Python 3文档:https://docs.python.org/3/library/os.html#os.listdir

import os

for filename in os.listdir("C:\\temp"):
    print  filename

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)

对于当前工作目录中的文件，无需指定路径

Python 2.7:

import os
os.listdir('.')

Python 3. x:

import os
os.listdir()

这是另一种选择。

os.scandir(path='.')

它返回os的迭代器。对应于path指定目录中的条目(以及文件属性信息)的DirEntry对象。

例子:

with os.scandir(path) as it:
    for entry in it:
        if not entry.name.startswith('.'):
            print(entry.name)

Using scandir() instead of listdir() can significantly increase the performance of code that also needs file type or file attribute information, because os.DirEntry objects expose this information if the operating system provides it when scanning a directory. All os.DirEntry methods may perform a system call, but is_dir() and is_file() usually only require a system call for symbolic links; os.DirEntry.stat() always requires a system call on Unix but only requires one for symbolic links on Windows.
