title: python error - NameError:name download_url is not defined
body: <p>I am trying to parse out the json response from a cURL command using a vendor's restful API. The full command is:</p>
  
  <pre><code>curl -s "url" -H "api" | python - c "import sys, json; print;(json.load(sys.stdin)["download_url"]);"
  </code></pre>
  
  <p>I keep getting an error that says NameError:name 'download_url' is not defined. Thoughts on how to fix this?</p>
