title: How to append output to an empty list without index, name and dtype?
body: <p>I am trying to append output to an empty list, but it also appends index, name, and dtype.
  This is the code:</p>
  <pre><code>China_pop=[]
  for year in range(1,101,1):
      x=(df[df.country==&quot;China&quot;][&quot;population&quot;]*((1+float(df[df.country==&quot;China&quot;][&quot;yearly_change&quot;].str.replace(&quot;%&quot;,&quot;&quot;,regex=True))/100))**year)
      China_pop.append(x)
  China_pop
  </code></pre>
  <p>and this is the output:</p>

  <p>I want to create a dataframe using this column, which ends up like this:

  <p>How can I append the output only? Is there a better way of creating this dataframe?</p>
