Select from pandas dataframe using boolean series/array : <p>I have a dataframe:</p>

<pre><code>             High    Low  Close
Date                           
2009-02-11  30.20  29.41  29.87
2009-02-12  30.28  29.32  30.24
2009-02-13  30.45  29.96  30.10
2009-02-17  29.35  28.74  28.90
2009-02-18  29.35  28.56  28.92
</code></pre>

<p>and a boolean series:</p>

<pre><code>     bools
1    True
2    False
3    False
4    True
5    False
</code></pre>

<p>how could I select from the dataframe using the boolean array to obtain result like:</p>

<pre><code>             High   
Date                           
2009-02-11  30.20  
2009-02-17  29.35  
</code></pre>
