"\xe7t\xe7" _is_ the same as "été" if you are using e. g. the ISO-8859-1
encoding, so chances are you will see été if you open the file in a text
editor without the need of prior conversions.

But I may be misunderstanding you and you really have "\\xe7t\\xe7" - in
that case you can use de/encode to switch between the two representations:

>>> "été".encode("string_escape")
>>> _.decode("string_escape")
>>> print _

(In the interpreter the result of the previous calculation is assigned to _
if it is not None)
