TypeError: far_away() missing 1 required positional argument: 'timedelta'

Hi Ava! Check out this line of code:

def far_away(timedelta):

The challenge says "write a function called far_away that takes one argument, a timedelta." You did that perfectly.

Next, it says: "Add that timedelta to datetime.datetime.now()"

Here's your problem:

def far_away(timedelta):
    datetime.timedelta() + datetime.datetime.now()

Look at the second line of code. That datetime.timedelta() is a different object. It's not the timedelta you're passing in as an argument.

You can reference that timedelta anywhere in your function by simply writing "timedelta".

Like this:

import datetime

def far_away(timedelta):
    return timedelta + datetime.datetime.now()

Lastly, you called the function in your original code (in the last line.)

import datetime
def far_away(timedelta):
    datetime.timedelta() + datetime.datetime.now()
    return datetime.datetime.now()
far_away()

You don't need to call the function. When you press "Check Work," the Treehouse Challenge calls the function behind the scenes.
