  <ol>
  <li><p>What are the meaningful differences between the following two Python interpreters apparently<a href="https://i.stack.imgur.com/SiMbt.png" rel="nofollow noreferrer">1</a> installed on my machine (2019 MacBook Pro with Catalina)?</p>
  
  <ul>
  <li><code>usr/local/opt/python/bin/python3.7</code></li>
  <li><code>usr/local/bin/python3</code></li>
  </ul></li>
  <li><p>Most importantly, which should I select as the interpreter for my IDE (Visual Studio Code)?</p></li>
  <li>Which interpreter is employed when running <code>$ python3</code> in terminal?</li>
  </ol>
  
  <p><strong>Context</strong> </p>
  
  <ul>
  <li>I just got a new 2019 MacBook Pro with OSX Catalina and noticed it came with a Python 2.7.10 interpreter installed. </li>
  <li>I <a href="https://wsvincent.com/install-python3-mac/" rel="nofollow noreferrer">installed Python 3 via Homebrew</a> given I mainly want to use Python 3 for my projects.</li>
  </ul>
