要glob多种文件类型，需要在循环中多次调用glob()函数。因为这个函数返回一个列表，所以需要连接这些列表。

例如，这个函数是这样的:

import glob
import os


def glob_filetypes(root_dir, *patterns):
    return [path
            for pattern in patterns
            for path in glob.glob(os.path.join(root_dir, pattern))]

简单的用法:

project_dir = "path/to/project/dir"
for path in sorted(glob_filetypes(project_dir, '*.txt', '*.mdown', '*.markdown')):
    print(path)

你也可以使用glob.iglob()来拥有一个迭代器:

返回一个迭代器，该迭代器产生与glob()相同的值，但实际上不会同时存储它们。

def iglob_filetypes(root_dir, *patterns):
    return (path
            for pattern in patterns
            for path in glob.iglob(os.path.join(root_dir, pattern)))

使用扩展列表并遍历

from os.path import join
from glob import glob

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

print(files)

这是一个Python 3.4+ pathlib解决方案:

exts = ".pdf", ".doc", ".xls", ".csv", ".ppt"
filelist = (str(i) for i in map(pathlib.Path, os.listdir(src)) if i.suffix.lower() in exts and not i.stem.startswith("~"))

此外，它会忽略所有以~开头的文件名。

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))

还有另一个解决方案(使用glob使用多个匹配模式获取路径，并使用reduce和add将所有路径组合到一个列表中):

import functools, glob, operator
paths = functools.reduce(operator.add, [glob.glob(pattern) for pattern in [
    "path1/*.ext1",
    "path2/*.ext2"]])

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)
