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') )

来这里寻求帮助后，我有了自己的解决方案，想和大家分享。它基于user2363986的答案，但我认为这更具可伸缩性。这意味着，即使您有1000个扩展，代码仍然看起来很优雅。
from glob import glob
directoryPath = "C:\\temp\\*."
fileExtensions = [ "jpg", "jpeg", "png", "bmp", "gif" ]
listOfFiles = []
for extension in fileExtensions:
listOfFiles.extend( glob( directoryPath + extension ))
for file in listOfFiles:
print(file) # Or do other stuff
其他回答
Glob返回一个列表:为什么不只是多次运行它并连接结果呢?
from glob import glob
project_files = glob('*.txt') + glob('*.mdown') + glob('*.markdown')
这是一个Python 3.4+ pathlib解决方案:
exts = ".pdf", ".doc", ".xls", ".csv", ".ppt"
filelist = (str(i) for i in map(pathlib.Path, os.listdir(src)) if i.suffix.lower() in exts and not i.stem.startswith("~"))
此外，它会忽略所有以~开头的文件名。
这对我很管用!
split('.')[-1]
上面的代码分开了文件名后缀(*.xxx)，所以它可以帮助你
for filename in glob.glob(folder + '*.*'):
print(folder+filename)
if filename.split('.')[-1] != 'tif' and \
filename.split('.')[-1] != 'tiff' and \
filename.split('.')[-1] != 'bmp' and \
filename.split('.')[-1] != 'jpg' and \
filename.split('.')[-1] != 'jpeg' and \
filename.split('.')[-1] != 'png':
continue
# Your code
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
import os
import glob
projectFiles = [i for i in glob.glob(os.path.join(projectDir,"*")) if os.path.splitext(i)[-1].lower() in ['.txt','.markdown','.mdown']]
Os.path.splitext将返回filename & .extension
filename, .extension = os.path.splitext('filename.extension')
.lower()将字符串转换为小写
