Aggiungere la lifetime
# Reference date reference_date = datetime.date(2018,4,1)# Add lifetime to the basetable basetable["lifetime"] = reference_date - basetable["member_since"] print(basetable.head())
donor_id member_since lifetime
1 2015-02-03 1153
2 2016-01-30 729
3 2016-02-23 768
Aggiungere il canale di contatto preferito (1)

reference_date = datetime.date(2018,4,1)# Select lines compliant with reference data contact_channel_reference_date = living_places[ (contact_channel["start_valid_date"]<=reference_date) & (living_places["end_valid_date"]>reference_date)]
Aggiungere il canale di contatto preferito (2)
# Add contact channel place to the basetable
basetable =
