getting unique date from python dataframe
<p>My dataframe has dates in format:
dd-mm-yy hh:mm:ss</p>

<p>E.g</p>

<pre><code>15-14-2016 08:05:10 
15-14-2016 08:15:30 
15-14-2016 10:45:22 
18-14-2016 06:23:10 
18-14-2016 07:37:30 
18-14-2016 12:48:22
</code></pre>

<p>There are around 1000 rows and </p>

<p>I used below code to get unique dates </p>

<pre><code>print pd.unique((df.Date).dt.strftime('%d-%m-%y'))
</code></pre>

<p>but my output seems to be 2 lists instead of just one:</p>

<pre><code>['15-04-16' '18-04-16' '19-04-16' '20-04-16' '21-04-16' '22-04-16']    
['15-04-16' '18-04-16' '19-04-16' '20-04-16' '21-04-16' '22-04-16']
</code></pre>

<p>Can anyone help</p>
