as in Unix, you know that the creation time is marked as the creation time of the inode, while the m time (so called modification time) is also the time to the inode. (creation of inode happens when you first create file/directory), while the modification bit of the inode indicate add/removing content to a directory or changing the content of a file);

To get the mtime and ctime, you can use the time module together with the os.path module, here is the cdoe that best show how you can query some time stamp associated with a file.

import os.path, time
import exceptions

class TypeError (Exception):
    pass


if __name__ == '__main__':
  if (len(os.sys.argv) < 1):
      raise TypeError()
  else:
      print "os.sys.argv[0]: %s" % os.sys.argv[0] # os.sys.argv[0] is the current file, in this case, file_ctime.py
  f = os.sys.argv[0]
  mtime = time.ctime(os.path.getmtime(f))
  ctime = time.ctime(os.path.getctime(f))
  print "Last modified : %s, last created time: %s" % (mtime, ctime)
