我如何在Python中获得给定目录中的所有文件(和目录)的列表?


当前回答

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.

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

下面是一行python版本:

import os
dir = 'given_directory_name'
filenames = [os.path.join(os.path.dirname(os.path.abspath(__file__)),dir,i) for i in os.listdir(dir)]

这段代码列出给定目录名中所有文件和目录的完整路径。

试试这个:

import os
for top, dirs, files in os.walk('./'):
    for nm in files:       
        print os.path.join(top, nm)

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

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()
