一个glob，许多扩展…但不完美的解决方案(可能匹配其他文件)。

filetypes = ['tif', 'jpg']

filetypes = zip(*[list(ft) for ft in filetypes])
filetypes = ["".join(ch) for ch in filetypes]
filetypes = ["[%s]" % ch for ch in filetypes]
filetypes = "".join(filetypes) + "*"
print(filetypes)
# => [tj][ip][fg]*

glob.glob("/path/to/*.%s" % filetypes)

链接结果:

import itertools as it, glob

def multiple_file_types(*patterns):
    return it.chain.from_iterable(glob.iglob(pattern) for pattern in patterns)

然后:

for filename in multiple_file_types("*.txt", "*.sql", "*.log"):
    # do stuff

如果你使用pathlib，试试这个:

import pathlib

extensions = ['.py', '.txt']
root_dir = './test/'

files = filter(lambda p: p.suffix in extensions, pathlib.Path(root_dir).glob('**/*'))

print(list(files))

import os
import glob

projectFiles = [i for i in glob.glob(os.path.join(projectDir,"*")) if os.path.splitext(i)[-1].lower() in ['.txt','.markdown','.mdown']]

Os.path.splitext将返回filename & .extension

filename, .extension = os.path.splitext('filename.extension')

.lower()将字符串转换为小写

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, [])

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))
