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)

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)

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)

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}'))

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。

你也可以像这样使用reduce():

import glob
file_types = ['*.txt', '*.mdown', '*.markdown']
project_files = reduce(lambda list1, list2: list1 + list2, (glob.glob(t) for t in file_types))

这将从glob.glob()为每个模式创建一个列表，并将它们简化为单个列表。
