Shippo - Python Package Async Issue

Question

I have imported the Shippo python package and I am trying to get their sample to work but I am running into the following error message (see below). I am running Python 3.7.2 on the most current API version.

Here is the error -

    Traceback (most recent call last):
      File "c:/Users/tom/Documents/PyProjects/goShippo/goShippoCreateLabels.py", line 1, in <module>
        import shippo
      File "C:\Python\lib\site-packages\shippo\__init__.py", line 8, in <module>
        from shippo.resource import (
      File "C:\Python\lib\site-packages\shippo\resource.py", line 303
        def get_rates(cls, object_id, async=False, api_key=None, currency=None, **params):
                                      ^
SyntaxError: invalid syntax

Here is the code -

import shippo

shippo.api_key = "shippo_test_123456789"

address_from = {

This package has Python version coverage up to 3.3. In versions 3.6+, "async" became a reserved keyword causing the syntax error you're getting.

Since "async" is a default parameter, the best workaround would be to explicitly change the "async" parameter to "asynchronous". This should at least avoid the syntax error until the package is updated for 3.6+ support.
