python subtract 14 days from date

from datetime import date, timedelta
dt = date.today() - timedelta(5)
print('Current Date :',date.today())
print('5 days before Current Date :',dt)

a_date = datetime.date(2015, 10, 10)
days = datetime.timedelta(5)

new_date = a_date - days
#Subtract 5 days from a_date


print(new_date)
#OUTPUT
#2015-10-05

df_test['Difference'] = (df_test['First_Date'] - df_test['Second Date']).dt.days
