你可以使用filter:

import os
import glob

projectFiles = filter(
    lambda x: os.path.splitext(x)[1] in [".txt", ".mdown", ".markdown"]
    glob.glob(os.path.join(projectDir, "*"))
)

例如，*.mp3和*.mp3。Flac在多个文件夹上，你可以做:

mask = r'music/*/*.[mf][pl][3a]*'
glob.glob(mask)

这个想法可以扩展到更多的文件扩展名，但您必须检查这些组合是否与这些文件夹上可能存在的任何其他不需要的文件扩展名匹配。所以要小心。

要自动将任意扩展列表组合到一个glob模式中，您可以执行以下操作:

def multi_extension_glob_mask(mask_base, *extensions):
    mask_ext = ['[{}]'.format(''.join(set(c))) for c in zip(*extensions)]
    if not mask_ext or len(set(len(e) for e in extensions)) > 1:
        mask_ext.append('*')
    return mask_base + ''.join(mask_ext)

mask = multi_extension_glob_mask('music/*/*.', 'mp3', 'flac', 'wma')
print(mask)  # music/*/*.[mfw][pml][a3]*

从前面的答案

glob('*.jpg') + glob('*.png')

这是一个较短的问题，

from glob import glob
extensions = ['jpg', 'png'] # to find these filename extensions

# Method 1: loop one by one and extend to the output list
output = []
[output.extend(glob(f'*.{name}')) for name in extensions]
print(output)

# Method 2: even shorter
# loop filename extension to glob() it and flatten it to a list
output = [p for p2 in [glob(f'*.{name}') for name in extensions] for p in p2]
print(output)

这应该有用:

import glob
extensions = ('*.txt', '*.mdown', '*.markdown')
for i in extensions:
    for files in glob.glob(i):
        print (files)

我也有同样的问题，这是我想到的

import os, sys, re

#without glob

src_dir = '/mnt/mypics/'
src_pics = []
ext = re.compile('.*\.(|{}|)$'.format('|'.join(['png', 'jpeg', 'jpg']).encode('utf-8')))
for root, dirnames, filenames in os.walk(src_dir):
  for filename in filter(lambda name:ext.search(name),filenames):
    src_pics.append(os.path.join(root, filename))

也许我遗漏了一些东西但如果只是简单的glob也许你可以这样做?

projectFiles = glob.glob(os.path.join(projectDir, '*.{txt,mdown,markdown}'))
