This should do it:

   import time
   import os
   firstdate = "200801010000"
   seconddate = "200801020000"
   def get_timestamp(s):
     return time.mktime(time.strptime(s, "%Y%m%d%H%M"))
   start = get_timestamp(firstdate)
   end = get_timestamp(seconddate)
   location = '/path/to/wherever/'
   files = [fname
     for fname in os.listdir(location)
     if start <=
       os.stat(os.path.join(location, fname)).st_mtime
       <= end
     ]
   print files

The magic is the the os.stat(f).st_mtime to determine when the 
associated timestamp, the os.listdir() to get the available files 
in a directory, and the list-comprehension to filter to only the 
ones you want.
