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
Glob返回一个列表:为什么不只是多次运行它并连接结果呢?
from glob import glob
project_files = glob('*.txt') + glob('*.mdown') + glob('*.markdown')

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']
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, [])

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))
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))
这对我很管用!
split('.')[-1]
上面的代码分开了文件名后缀(*.xxx)，所以它可以帮助你
for filename in glob.glob(folder + '*.*'):
print(folder+filename)
if filename.split('.')[-1] != 'tif' and \
filename.split('.')[-1] != 'tiff' and \
filename.split('.')[-1] != 'bmp' and \
filename.split('.')[-1] != 'jpg' and \
filename.split('.')[-1] != 'jpeg' and \
filename.split('.')[-1] != 'png':
continue
