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")

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。

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))

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)

例如，*.mp3和*.mp3。Flac在多个文件夹上，你可以做:

mask = r'music/*/*.[mf][pl][3a]*'
glob.glob(mask)

这个想法可以扩展到更多的文件扩展名，但您必须检查这些组合是否与这些文件夹上可能存在的任何其他不需要的文件扩展名匹配。所以要小心。

要自动将任意扩展列表组合到一个glob模式中，您可以执行以下操作:

def multi_extension_glob_mask(mask_base, *extensions):
    mask_ext = ['[{}]'.format(''.join(set(c))) for c in zip(*extensions)]
    if not mask_ext or len(set(len(e) for e in extensions)) > 1:
        mask_ext.append('*')
    return mask_base + ''.join(mask_ext)

mask = multi_extension_glob_mask('music/*/*.', 'mp3', 'flac', 'wma')
print(mask)  # music/*/*.[mfw][pml][a3]*

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
