Just need to set the index of the field you'd like to resample by, here's some examples

In [36]: df.set_index('recd').resample('1M',how='sum')
Out[36]: 
                 price  qty
recd                       
2012-07-31   64.151194    9
2012-08-31   93.476665    7
2012-09-30   94.193027    7
2012-10-31         NaN  NaN
2012-11-30         NaN  NaN
2012-12-31   12.353405    6
2013-01-31         NaN  NaN
2013-02-28  129.586697    7
2013-03-31         NaN  NaN
2013-04-30         NaN  NaN
2013-05-31  211.979583   13

In [37]: df.set_index('recd').resample('1M',how='count')
