Interpreter version selection error

Environment data

VS Code version: 1.19.1 Python Extension version: 0.9.1 Python Version: 3.6.3 OS and version: MacOS 10.12.6

Actual behavior

Run correctly

Expected behavior

Syntax error

Steps to reproduce:

if use such code on the python3 file:

from abc import ABCMeta, abstractmethod

class class_name(metaclass=ABCMeta):
    def __init__(self):
        pass

when click run button at the top right corner, the running result goes syntax error:

 class class_name(metaclass=ABCMeta):
                             ^
SyntaxError: invalid syntax

even I have chosen the version 3.6.3 as interpreter.

Might be a bug?
