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') )

例如:
import glob
lst_img = []
base_dir = '/home/xy/img/'
# get all the jpg file in base_dir
lst_img += glob.glob(base_dir + '*.jpg')
print lst_img
# ['/home/xy/img/2.jpg', '/home/xy/img/1.jpg']
# append all the png file in base_dir to lst_img
lst_img += glob.glob(base_dir + '*.png')
print lst_img
# ['/home/xy/img/2.jpg', '/home/xy/img/1.jpg', '/home/xy/img/3.png']
一个函数:
import glob
def get_files(base_dir='/home/xy/img/', lst_extension=['*.jpg', '*.png']):
"""
:param base_dir:base directory
:param lst_extension:lst_extension: list like ['*.jpg', '*.png', ...]
:return:file lists like ['/home/xy/img/2.jpg','/home/xy/img/3.png']
"""
lst_files = []
for ext in lst_extension:
lst_files += glob.glob(base_dir+ext)
return lst_files
其他回答
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。
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}'))
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
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))
例如:
import glob
lst_img = []
base_dir = '/home/xy/img/'
# get all the jpg file in base_dir
lst_img += glob.glob(base_dir + '*.jpg')
print lst_img
# ['/home/xy/img/2.jpg', '/home/xy/img/1.jpg']
# append all the png file in base_dir to lst_img
lst_img += glob.glob(base_dir + '*.png')
print lst_img
# ['/home/xy/img/2.jpg', '/home/xy/img/1.jpg', '/home/xy/img/3.png']
一个函数:
import glob
def get_files(base_dir='/home/xy/img/', lst_extension=['*.jpg', '*.png']):
"""
:param base_dir:base directory
:param lst_extension:lst_extension: list like ['*.jpg', '*.png', ...]
:return:file lists like ['/home/xy/img/2.jpg','/home/xy/img/3.png']
"""
lst_files = []
for ext in lst_extension:
lst_files += glob.glob(base_dir+ext)
return lst_files
