I've used something like the below to find the most recent file in a
directory tree (it also works for pulling other attributes like the
file-size from os.stat() results).
-tkc
import os
from operator import attrgetter
def dir_iter(root):
for fullpath in (
os.path.join(path, dir_)
for path, dirs, files in os.walk(root)
for dir_ in dirs
):
if os.path.isdir(fullpath):
yield fullpath
def find_latest(root,
which_time=attrgetter("st_mtime")
):
return max(dir_iter(root),
key=lambda fullpath: which_time(os.stat(fullpath))
)
if __name__ == "__main__":
from sys import argv
if len(argv) > 1:
root = argv[1]
else:
root = '.'
print(find_latest(root))
print(find_latest(root, which_time=attrgetter("st_ctime")))
