title: Tweepy won't install on python 3.7; shows "syntax error"
body: <p>Before I begin, I'd like to preface that I'm relatively new to python, and haven't had to use it much before this little project of mine. I'm trying to make a twitter bot as part of an art project, and I can't seem to get tweepy to import. I'm using macOS High Sierra and Python 3.7. I first installed tweepy by using </p>
  
  <pre><code>pip3 install tweepy
  </code></pre>
  
  <p>and this appeared to work, as I'm able to find the tweepy files in finder. However, when I simply input </p>
  
  <pre><code>import tweepy
  </code></pre>
  
  <p>into the IDLE, I get this error:</p>
  
  <pre><code>Traceback (most recent call last):
  File "/Users/jacobhill/Documents/CicadaCacophony.py", line 1, in &lt;module&gt;
    import tweepy
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/tweepy/__init__.py", line 17, in &lt;module&gt;
    from tweepy.streaming import Stream, StreamListener
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/tweepy/streaming.py", line 358
    def _start(self, async):
                           ^
  SyntaxError: invalid syntax
  </code></pre>
  
  <p>Any idea on how to remedy this? I've looked at other posts on here and the other errors seem to be along the lines of "tweepy module not found", so I don't know what to do with my error. Thanks!</p>
