<p>How to convert list object to Pandas Dataframe with defined format?</p>

<p>Printed list has this output (Jupyter):</p>

<pre><code>(u'variable',    price  threshold
0   13.5      100.0
1   10.0        NaN)
(u'standard',    price  threshold
0   12.5      300.0
1   11.0        NaN)
(u'fixed',    price  threshold
0   14.5      250.0
1   10.1      200.0
2    9.0        NaN)
(u'standing-charge',    price
0      9)
</code></pre>

<p>Converted to Pandas Dataframe:</p>

<pre><code>    0               1
0   variable        price threshold 0 13.5 100.0 1 10...
1   standard        price threshold 0 12.5 300.0 1 11...
2   fixed           price threshold 0 14.5 250.0 1 10...
3   standing-charge price 0 9
</code></pre>

<p>I need:</p>

<pre><code>type       price  threshold
variable    13.5   100
variable    10.0   NaN
...
</code></pre>

<p>Please, help ;)</p>
