最简单的方法是使用itertools.chain

from pathlib import Path
import itertools

cwd = Path.cwd()

for file in itertools.chain(
    cwd.rglob("*.txt"),
    cwd.rglob("*.md"),
):
    print(file.name)

也许有更好的办法，但是:

import glob
types = ('*.pdf', '*.cpp') # the tuple of file types
files_grabbed = []
for files in types:
    files_grabbed.extend(glob.glob(files))

# files_grabbed is the list of pdf and cpp files

也许还有其他的方法，所以等待别人提出更好的答案。

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")

不是glob，这里是另一种使用列表理解的方式:

extensions = 'txt mdown markdown'.split()
projectFiles = [f for f in os.listdir(projectDir) 
                  if os.path.splitext(f)[1][1:] in extensions]

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

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
        # Your code
