How add date to current date time Python

 I have created a helper function to get future or past day DateTime. 

def add_days_now_datetime(days=0):
    date_N_days_ago = datetime.datetime.now() + datetime.timedelta(days=days)
    return date_N_days_ago

Calling this function we can get current DateTime +/- DateTime.

Example :

datetime.datetime.now()

datetime.datetime(2021, 8, 30, 20, 2, 52, 827013)

So if we call the above function without passing any number we will get the same output.

add_days_now_datetime()

datetime.datetime(2021, 8, 30, 20, 4, 23, 582737)

We get the same output because by default value is 0.

Now if I want to get a 5-day future same time DateTime then - 

add_days_now_datetime(5)

datetime.datetime(2021, 9, 4, 20, 4, 53, 156255)

If we want to get past same time DateTime then - 

add_days_now_datetime(-5)

datetime.datetime(2021, 8, 25, 20, 5, 18, 427882)
