import os
def get_immediate_subdirectories(a_dir):
    return [name for name in os.listdir(a_dir)
            if os.path.isdir(os.path.join(a_dir, name))]

import glob
import os

def child_dirs(path):
     cd = os.getcwd()        # save the current working directory
     os.chdir(path)          # change directory 
     dirs = glob.glob("*/")  # get all the subdirectories
     os.chdir(cd)            # change directory to the script original location
     return dirs

child_dirs函数的作用是:获取一个目录的路径，并返回其中直接子目录的列表。

dir
 |
  -- dir_1
  -- dir_2

child_dirs('dir') -> ['dir_1', 'dir_2']

def get_folders_in_directories_recursively(directory, index=0):
    folder_list = list()
    parent_directory = directory

    for path, subdirs, _ in os.walk(directory):
        if not index:
            for sdirs in subdirs:
                folder_path = "{}/{}".format(path, sdirs)
                folder_list.append(folder_path)
        elif path[len(parent_directory):].count('/') + 1 == index:
            for sdirs in subdirs:
                folder_path = "{}/{}".format(path, sdirs)
                folder_list.append(folder_path)

    return folder_list

下面的函数可以被调用为:

get_folders_in_directores_recurrecursive (directory, index=1) ->给出了第一层的文件夹列表

get_folders_in_directores_recurrecursive (directory) ->给出所有子文件夹

import os
def get_immediate_subdirectories(a_dir):
    return [name for name in os.listdir(a_dir)
            if os.path.isdir(os.path.join(a_dir, name))]

这里有一种方法:

import os
import shutil

def copy_over(path, from_name, to_name):
  for path, dirname, fnames in os.walk(path):
    for fname in fnames:
      if fname == from_name:
        shutil.copy(os.path.join(path, from_name), os.path.join(path, to_name))


copy_over('.', 'index.tpl', 'index.html')

我必须提到path.py库，我经常使用它。

获取直接子目录变得如此简单:

my_dir.dirs ()

完整的工作示例是:

from path import Path

my_directory = Path("path/to/my/directory")

subdirs = my_directory.dirs()

注意:my_directory仍然可以作为字符串操作，因为Path是string的子类，但提供了一堆有用的方法来操作路径
