Syntax error on Raspberry Pi

• bleak version: 0.2.0
• Python version: 3.5.3
• Operating System: Raspbian Stretch

Description

Trying to run the discovery example from usage section in the documentation in a virtualenv on a raspberry pi with default python 3.5.3 installed.

What I Did

Saved the discovery code from the docs to discover.py

python3 -m venv venv
. venv/bin/activate
pip install bleak
 python3 discover.py
Traceback (most recent call last):
  File "discover.py", line 2, in <module>
