Get the last modified date of a directory (including subdirectories) using Python?

Question

I am trying to get the last modification date and time of a directory. while doing that I want to include the last modified date of the sub directories as well.

I could find some topics related to this question.(How to get file creation & modification date/times in Python?) but all of those just gives the last modified time of the root directory without considering the sub directories.

import os.path, time
print "last modified: %s" % time.ctime(os.path.getmtime(file))
print "created: %s" % time.ctime(os.path.getctime(file))

These lines of code just gives the last modified time of the root directory without considering the sub directories. Please help me on this.

This should do what you ask:

import os
import time

print time.ctime(max(os.stat(root).st_mtime for root,_,_ in os.walk('/tmp/x')))

But I see you use os.path.getmtime(). So you are probably looking for this:

print time.ctime(max(os.path.getmtime(root) for root,_,_ in os.walk('/tmp/x')))
