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')

你也可以像这样使用reduce():

import glob
file_types = ['*.txt', '*.mdown', '*.markdown']
project_files = reduce(lambda list1, list2: list1 + list2, (glob.glob(t) for t in file_types))

这将从glob.glob()为每个模式创建一个列表，并将它们简化为单个列表。

下面的函数_glob用于多个文件扩展名。

import glob
import os
def _glob(path, *exts):
    """Glob for multiple file extensions

    Parameters
    ----------
    path : str
        A file name without extension, or directory name
    exts : tuple
        File extensions to glob for

    Returns
    -------
    files : list
        list of files matching extensions in exts in path

    """
    path = os.path.join(path, "*") if os.path.isdir(path) else path + "*"
    return [f for files in [glob.glob(path + ext) for ext in exts] for f in files]

files = _glob(projectDir, ".txt", ".mdown", ".markdown")

与@BPL相同的答案(计算效率高)，但它可以处理任何glob模式，而不是扩展:

import os
from fnmatch import fnmatch

folder = "path/to/folder/"
patterns = ("*.txt", "*.md", "*.markdown")

files = [f.path for f in os.scandir(folder) if any(fnmatch(f, p) for p in patterns)]

这种解决方案既高效又方便。它还与glob的行为紧密匹配(请参阅文档)。

注意，使用内置包pathlib会更简单:

from pathlib import Path

folder = Path("/path/to/folder")
patterns = ("*.txt", "*.md", "*.markdown")

files = [f for f in folder.iterdir() if any(f.match(p) for p in patterns)]

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, [])

这应该有用:

import glob
extensions = ('*.txt', '*.mdown', '*.markdown')
for i in extensions:
    for files in glob.glob(i):
        print (files)
