title: what is ".==" in julia and its equivalent in python?
body: <p>I'm new to julia and I'm working on to rewrite julia code to python code.
  And I saw the some codes using <code>.==</code> expression. I couldn't understand what this means. So I searched it on web but couldn't find an answer.
  Can someone tell me what is <code>.==</code> in julia and its equivalent in python?</p>
  <p>fyi, it was written like below.</p>
  <pre><code>x = sum(y .== 0)  # y is array
  </code></pre>
