快速获取文件的路径列表，而且是绝对路径

from glob import glob

data_dir = r'C:\Users\lab\git\NeuLF\dataset\CanClip\images_4'
images = sorted(glob(f'{data_dir}/*.jpg') + glob(f'{data_dir}/*.png'))
# ['C:\\Users\\lab\\git\\NeuLF\\dataset\\CanClip\\images_4\\img001.png',
#  'C:\\Users\\lab\\git\\NeuLF\\dataset\\CanClip\\images_4\\img002.png']

These patterns: glob.glob("../images")错，glob.glob("../images/*")对

• Asterisk (*): Matches zero or more characters.
• Question mark (?): Matches exactly one character.

递归查找

from glob import iglob

path = '/Users/tara/ml_guides/' + '**/*.ipynb'
for file in iglob(path, recursive=True):
    ...

we can use glob to find all files in a directory and its subdirectories that match a search pattern.

• the argument recursive=True tells glob to search all sub-directories. When the recursive argument is set to False(default), we only search in the folder specified in our search path.

• iglob differs from glob in that it returns an iterator “which yields the same values as glob without storing them all simultaneously,”
