With python, how to read the "date created" file?

I am writing a short script in python that scans the list of folders for image files and then reorganizes them.

One of the possible ways to organize them that I want to have is the date they were created.

I'm currently trying to read the image creation date as follows

import os.path, time

f = open("hi.jpg")
data = f.read()
f.close()
print "last modified: %s" % time.ctime(os.path.getmtime(f))
print "created: %s" % time.ctime(os.path.getctime(f))

But I get an error

Traceback (most recent call last):
  File "TestEXIFread.py", line 6, in <module>
    print "last modified: %s" % time.ctime(os.path.getmtime(f))
  File "/usr/lib/python2.7/genericpath.py", line 54, in getmtime
    return os.stat(filename).st_mtime
TypeError: coercing to Unicode: need string or buffer, file found

Can someone tell me what that means?

You need to use a string for the file name instead of the file object.

>>> import os.path, time
>>> f = open('test.test')
>>> data = f.read()
>>> f.close()
>>> print "last modified: %s" % time.ctime(os.path.getmtime('test.test'))
last modified: Fri Apr 13 20:39:21 2012
>>> print "created : %s" % time.ctime(os.path.getctime('test.test'))
created : Fri Apr 13 20:39:21 2012
