title: How can I map True/False to 1/0 in a Pandas DataFrame?
body: <p>I have a column in python <code>pandas</code> DataFrame that has boolean <code>True</code>/<code>False</code> values, but for further calculations I need <code>1</code>/<code>0</code> representation. Is there a quick <code>pandas</code>/<code>numpy</code> way to do that?</p>
