Wed Jan 20 08:01:21 CST 2010
I have an array with the leading column a series of datetime objects. It

Right now I do this:
A = array with column 0 datetime objects
January = [i for i in A if i.month ==1 ]
It works, but I would rather use np.where and get indices and not have to
convert my list back into an array.
