有没有更好的方法来使用glob。Glob在python中获取多个文件类型的列表,如.txt, .mdown和.markdown?现在我有这样的东西:

projectFiles1 = glob.glob( os.path.join(projectDir, '*.txt') )
projectFiles2 = glob.glob( os.path.join(projectDir, '*.mdown') )
projectFiles3 = glob.glob( os.path.join(projectDir, '*.markdown') )

当前回答

from glob import glob

files = glob('*.gif')
files.extend(glob('*.png'))
files.extend(glob('*.jpg'))

print(files)

如果你需要指定一个路径,循环匹配模式,并保持连接在循环中简单:

from os.path import join
from glob import glob

files = []
for ext in ('*.gif', '*.png', '*.jpg'):
   files.extend(glob(join("path/to/dir", ext)))

print(files)

其他回答

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

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}'))

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))

最简单的方法是使用itertools.chain

from pathlib import Path
import itertools

cwd = Path.cwd()

for file in itertools.chain(
    cwd.rglob("*.txt"),
    cwd.rglob("*.md"),
):
    print(file.name)
files = glob.glob('*.txt')
files.extend(glob.glob('*.dat'))
