The example worked in interpreter but not when I write in a `.py` file. ```py from __future__ import barry_as_FLUFL import sys print(sys.version) "Ruby" != "Python" #This is OK ``` ```py from __future__ import barry_as_FLUFL import sys print(sys.version) "Ruby" <> "Python" #But this raise a exception ``` output 1: ```sh 3.6.5 |Anaconda, Inc.| (default, Mar 29 2018, 13:32:41) [MSC v.1900 64 bit (AMD64)] ``` output 2: ```sh File "test.py", line 4 "Ruby" <> "Python" ^ SyntaxError: invalid syntax ```
