title: convert list of tuples into single column of pandas dataframe?
body: <p>I have a list of tuple like this :</p>
  <pre><code>list_t = [(1,2),(1,7),(1,8),(2,6),(5,8)]
  </code></pre>
  <p>I want to make data frame out this but just one column:</p>
  <p><a href="https://i.stack.imgur.com/gbiMe.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/gbiMe.png" alt="enter image description here" /></a></p>
  <p>Currently using this</p>
  <pre><code>df_com = pd.DataFrame(list_t,columns=[&quot;so&quot;,&quot;des&quot;])
  </code></pre>
  <p>but then I have to join them again so operation cost is increased.</p>
  <p>Thank you for your help</p>
