program creek seems to be a good site for handy references of python modules. For e.g. when I wanted to know how to use Stratified Shuffle module, the examples shown on this page were very useful.

14 days ago

This is the python way of calculating the date that is 14 days ago.

import datetime
(datetime.datetime.now() - datetime.timedelta(days = 14)).date()

And this is pandas way of getting the same results:

import pandas as pd
(pd.datetime.today() - pd.offsets.Day(14)).floor('D')
