有没有更好的方法来使用glob。Glob在python中获取多个文件类型的列表,如.txt, .mdown和.markdown?现在我有这样的东西:

projectFiles1 = glob.glob( os.path.join(projectDir, '*.txt') )
projectFiles2 = glob.glob( os.path.join(projectDir, '*.mdown') )
projectFiles3 = glob.glob( os.path.join(projectDir, '*.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")

其他回答

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, [])

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")

我也有同样的问题,这是我想到的

import os, sys, re

#without glob

src_dir = '/mnt/mypics/'
src_pics = []
ext = re.compile('.*\.(|{}|)$'.format('|'.join(['png', 'jpeg', 'jpg']).encode('utf-8')))
for root, dirnames, filenames in os.walk(src_dir):
  for filename in filter(lambda name:ext.search(name),filenames):
    src_pics.append(os.path.join(root, filename))

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。

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))
