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') )

链接结果:
import itertools as it, glob
def multiple_file_types(*patterns):
return it.chain.from_iterable(glob.iglob(pattern) for pattern in patterns)
然后:
for filename in multiple_file_types("*.txt", "*.sql", "*.log"):
# do stuff

还有另一个解决方案(使用glob使用多个匹配模式获取路径，并使用reduce和add将所有路径组合到一个列表中):
import functools, glob, operator
paths = functools.reduce(operator.add, [glob.glob(pattern) for pattern in [
"path1/*.ext1",
"path2/*.ext2"]])
使用扩展列表并遍历
from os.path import join
from glob import glob
files = []
extensions = ['*.gif', '*.png', '*.jpg']
for ext in extensions:
files.extend(glob(join("path/to/dir", ext)))
print(files)
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)
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)
from glob import glob
files = glob('*.gif')
files.extend(glob('*.png'))
files.extend(glob('*.jpg'))
print(files)
如果你需要指定一个路径，循环匹配模式，并保持连接在循环中简单:
from os.path import join
from glob import glob
files = []
for ext in ('*.gif', '*.png', '*.jpg'):
files.extend(glob(join("path/to/dir", ext)))
print(files)
