这招对我很管用:

import glob
images = glob.glob('*.JPG' or '*.jpg' or '*.png')

您可以尝试制作一个手动列表，将现有扩展与所需扩展进行比较。

ext_list = ['gif','jpg','jpeg','png'];
file_list = []
for file in glob.glob('*.*'):
  if file.rsplit('.',1)[1] in ext_list :
    file_list.append(file)

你可以用这个:

project_files = []
file_extensions = ['txt','mdown','markdown']
for file_extension in file_extensions:
    project_files.extend(glob.glob(projectDir  + '*.' + file_extension))

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

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))

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
