computing the mean for python datetime

Question

I have a datetime attribute:

d = {
    \'DOB\': pd.Series([
        datetime.datetime(2014, 7, 9),
        datetime.datetime(2014, 7, 15),
        np.datetim         


        

Answer 1

Datetime math supports some standard operations:

a = datetime.datetime(2014, 7, 9)
b = datetime.datetime(2014, 7, 15)
c = (b - a)/2

# here c will be datetime.timedelta(3)

a + c
Out[7]: datetime.datetime(2014, 7, 12, 0, 0)

So you can write a function that, given two datetimes, subtracts the lesser form the greater and adds half of the difference to the lesser. Apply this function to your dataframe, and shazam!
