Find files/folders that are modified after a specific date in Python

问题

Problem ; find files/folders that are changed after a specific date from a directory structure and copy these to another location (as stated clearly in title as well) (:

By the following ;

def mod():
     """Find files modified today, given a file path."""
     latest = 0
     now = time.strftime('%Y-%m-%d', time.localtime())
     dir = "/home/y33t/"
     for fname in os.listdir(dir):
         if fname.endswith(''):
             modtime = os.stat(os.path.join(dir, fname)).st_mtime
             if modtime > latest:
                 latest = modtime
                 out = time.strftime('%Y-%m-%d', time.localtime(latest))
                 if out == now:
                     print fname, "has changed today. "
                 else:
                     pass

I can determine which files are changed at a specific date and copy these to a location. What I would like to achieve is to keep the directory structure as well. An example is as following ;

/testfolder
..somefile1
..somefile2
../testfolder2
....somefile3
....somefile4

and so on...

lets say somefile3 is changed at the specified date and I will save it to another location but while saving, cascaded directory structure should be maintained as well. How can I achieve this in an elegant way ?

回答1:

Before copying, you should solve reading. os.listdir will give you only one level while os.walk will let you go over each file in every depth.

To copy, you will first use os.makedirs(target-path) to create all the folders from root to target folder at any depth then you will use shutil.copy to copy the file.
