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') )
与@BPL相同的答案(计算效率高),但它可以处理任何glob模式,而不是扩展:
import os
from fnmatch import fnmatch
folder = "path/to/folder/"
patterns = ("*.txt", "*.md", "*.markdown")
files = [f.path for f in os.scandir(folder) if any(fnmatch(f, p) for p in patterns)]
这种解决方案既高效又方便。它还与glob的行为紧密匹配(请参阅文档)。
注意,使用内置包pathlib会更简单:
from pathlib import Path
folder = Path("/path/to/folder")
patterns = ("*.txt", "*.md", "*.markdown")
files = [f for f in folder.iterdir() if any(f.match(p) for p in patterns)]
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, [])
