TypeError: expected a character buffer object

Question

I am trying to translate file name without number. I am getting following error:

>>> file ="1abc89.jpg"
>>> os.rename(file,file.translate(None,"0123456789"))
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: expected a character buffer object

I tried searching few threads, but am not able to get the point.

Python 3.4:

>>> import os
>>> name = '1abc89.jpg'
>>> name.translate(str.maketrans('','','0123456789'))
'abc.jpg'
>>> os.rename(name,name.translate(str.maketrans('','','0123456789')))

Python 2.7:

>>> import os
>>> name = '1abc89.jpg'
>>> name.translate(None,'0123456789')
'abc.jpg'
>>> os.rename(name,name.translate(None,'0123456789'))
