Intersection of multiple pandas dataframes
<p>I have a number of dataframes (100) in a list as:</p>

<pre><code>frameList = [df1,df2,..,df100]
</code></pre>

<p>Each dataframe has the two columns <code>DateTime</code>, <code>Temperature</code>.</p>

<p>I want to intersect all the dataframes on the common <code>DateTime</code> column and get all their  <code>Temperature</code> columns combined/merged into one big dataframe: Temperature from df1, Temperature from df2, Temperature from df3, .., Temperature from df100.</p>

<p>(pandas <code>merge</code> doesn't work as I'd have to compute multiple (99) pairwise intersections).</p>
