import os    
import glob
import operator
from functools import reduce

types = ('*.jpg', '*.png', '*.jpeg')
lazy_paths = (glob.glob(os.path.join('my_path', t)) for t in types)
paths = reduce(operator.add, lazy_paths, [])

还有另一个解决方案(使用glob使用多个匹配模式获取路径，并使用reduce和add将所有路径组合到一个列表中):

import functools, glob, operator
paths = functools.reduce(operator.add, [glob.glob(pattern) for pattern in [
    "path1/*.ext1",
    "path2/*.ext2"]])

一句俏皮话，只是为了好玩。

folder = "C:\\multi_pattern_glob_one_liner"
files = [item for sublist in [glob.glob(folder + ext) for ext in ["/*.txt", "/*.bat"]] for item in sublist]

输出:

['C:\\multi_pattern_glob_one_liner\\dummy_txt.txt', 'C:\\multi_pattern_glob_one_liner\\dummy_bat.bat']

你也可以像这样使用reduce():

import glob
file_types = ['*.txt', '*.mdown', '*.markdown']
project_files = reduce(lambda list1, list2: list1 + list2, (glob.glob(t) for t in file_types))

这将从glob.glob()为每个模式创建一个列表，并将它们简化为单个列表。

例如:

import glob
lst_img = []
base_dir = '/home/xy/img/'

# get all the jpg file in base_dir 
lst_img += glob.glob(base_dir + '*.jpg')
print lst_img
# ['/home/xy/img/2.jpg', '/home/xy/img/1.jpg']

# append all the png file in base_dir to lst_img
lst_img += glob.glob(base_dir + '*.png')
print lst_img
# ['/home/xy/img/2.jpg', '/home/xy/img/1.jpg', '/home/xy/img/3.png']

一个函数:

import glob
def get_files(base_dir='/home/xy/img/', lst_extension=['*.jpg', '*.png']):
    """
    :param base_dir:base directory
    :param lst_extension:lst_extension: list like ['*.jpg', '*.png', ...]
    :return:file lists like ['/home/xy/img/2.jpg','/home/xy/img/3.png']
    """
    lst_files = []
    for ext in lst_extension:
        lst_files += glob.glob(base_dir+ext)
    return lst_files

对于glob，这是不可能的。你只能使用: *匹配所有内容 ？ 匹配任何单个字符 [seq]匹配seq中的任意字符 [!Seq]匹配任何不在Seq中的字符

使用操作系统。Listdir和regexp检查模式:

for x in os.listdir('.'):
  if re.match('.*\.txt|.*\.sql', x):
    print x
