title: Change tuple values into dataframe
body: <p>I have a dataframe that looks like this (imaginary data for illustration):
  <a href="https://i.stack.imgur.com/w5Pbz.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/w5Pbz.png" alt="enter image description here" /></a></p>
  <p>I would like to transform these tuple paired(?) values like the following dataframe:</p>
  <pre><code>Date       Age      Sex       Height(cm)  ...
  20150210   23       Female    209         ...
  20150421   31       Male      301         ...
  </code></pre>
  <p>what could be the easiest way to transform it into the dataframe I desire without typing in every column names manually?</p>
  <p>thanks.</p>
