Python arrow add hour/minutes/etc vs replace

Question

I wanted to use arrow vs datetime in Python, and I want to convert the following example to arrow:

end_date = start_date + timedelta(days=5)

The only thing I see in the arrow docs is:

start_date.replace(weeks=+3)

But I want to assign end_date with 5 days more than the start_date - not changing the existing start_date

I don't want to write i.e:

end_date = start_date
end_date.replace(days=+5)

I want to do it in a one-liner ... any idea ?

Answer 1

start_date.replace doesn't alter start_date, it returns a new object. So you can just assign that to a new name:

end_date = start_date.replace(days=+5)

Reading the docs is useful.

Answer 2

Ok, With arrow i assumed the todays date like

import arrow
start_date = arrow.utcnow()

Now I want to end_date is +5 days more to start_date, while start_date is unchanged.

end_date = start_date.replace(days=+5)

Is not this solved your problem?
