python subtract days from date

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

from datetime import datetime

def days_between(d1, d2):
    d1 = datetime.strptime(d1, "%Y-%m-%d")
    d2 = datetime.strptime(d2, "%Y-%m-%d")
    return abs((d2 - d1).days)

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

# import datetime module
from datetime import datetime,timedelta

currentTimeDate = datetime.now() - timedelta(10)
subDate = currentTimeDate.strftime('%Y-%m-%d')

print(subDate)

//Output:
