Calculates the date of `n` days from the given date.
|
|
|
|
- Use `datetime.timedelta` and the `+` operator to calculate the new `datetime.datetime` value after adding `n` days to `d`.
|
|
- Omit the second argument, `d`, to use a default value of `datetime.today()`.
|
|
|
|
```py
|
|
from datetime import datetime, timedelta
|
|
|
|
def add_days(n, d = datetime.today()):
|
|
return d + timedelta(n)
|
|
```
|
|
|
|
```py
|
|
from datetime import date
|
|
|
|
add_days(5, date(2020, 10, 25)) # date(2020, 10, 30)
|
|
add_days(-5, date(2020, 10, 25)) # date(2020, 10, 20)
|
|
```
