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)))

import glob
import pandas as pd

df1 = pd.DataFrame(columns=['A'])
for i in glob.glob('C:\dir\path\*.txt'):
    df1 = df1.append({'A': i}, ignore_index=True)
for i in glob.glob('C:\dir\path\*.mdown'):
    df1 = df1.append({'A': i}, ignore_index=True)
for i in glob.glob('C:\dir\path\*.markdown):
    df1 = df1.append({'A': i}, ignore_index=True)

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')

也许我遗漏了一些东西但如果只是简单的glob也许你可以这样做?

projectFiles = glob.glob(os.path.join(projectDir, '*.{txt,mdown,markdown}'))

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")

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。
