import tweepy error on Mac

Question

I am running tweepy successfully on Windows 10 but when I run the same app on my Mac it crashes with the error below in Idle after the import tweepy statement. It seems to be something inside the tweepy module which I am not sure how to fix.

Traceback (most recent call last):
  File "/Users/arnoldrosielle/Desktop/PythonScripts/Twitter_Likes.py", line 9, in <module>
    import tweepy
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/tweepy/__init__.py", line 17, in <module>
    from tweepy.streaming import Stream, StreamListener

    def _start(self, async):
                         ^
SyntaxError: invalid syntax

OK - so no real responses on StackOverflow so I looked a bit harder on the web and found this from here https://github.com/tweepy/tweepy/issues/1017

The same issue but on Windows10 x64 python3.7 beta, on python3.6 it works fine, so seems like incompatibility with python 3.7? Okay found the solution. Apparently async cannot be used as an argument name in Python 3.7 So open streaming.py and replace #async with async_ it fixed the error for me."

I got into streaming.py on my mac and replaced async with async_ (all occurrences). That took care of the problem. So indeed async cannot be used as a variable on MacOS but it is fine on Windows. Seems like a simple fix for the developer of tweepy to change it from async to async_.
