title: lightweight alternative for pandas
body: <p>I am trying to create an AWS lambda function written in Python.<br>
  Lambda function create fails with following error:</p>
  
  <blockquote>
    <p>Unzipped file size must be smaller than 262144000 bytes.</p>
  </blockquote>
  
  <p>Following is my requirements.txt</p>
  
  <pre><code>numpy
  pandas
  pprint
  pint
  flask
  scipy
  gunicorn
  pydblite
  jsonschema
  matplotlib
  sklearn
  </code></pre>
  
  <p>After removing all <code>test</code>, <code>*.pyc</code> and <code>*-info*</code> files following packages are the top contributors to the volume.</p>
  
  <pre><code>scipy  126M
  pandas 64M
  numpy  64M
  matplotlib 29M
  </code></pre>
  
  <p>I have replaced pandas' read_excel with <code>xlsx</code>. </p>
  
  <p>If there is any way I can get size reduced version of packages, that would be great.
  Otherwise, looking for alternatives of:</p>
  
  <ul>
  <li>pandas's <code>DataFrame</code></li>
  </ul>
