Python Dates and Times in Python (2014) Let's Build a Timed Quiz App Harder Time Machine

Need help with this challenge that has timedeltas in it.

I'm not sure what's wrong with my code. It keeps returning an error message regarding the keyword "time." Any help is appreciated!

time_machine.py
import datetime

starter = datetime.datetime(2015, 10, 21, 16, 29)

def time_machine(int1, time):
    if time == "years":
        time_ahead = datetime.timedelta(days=365*int1)
        return(starter + time_ahead)
    else:
        time_ahead = datetime.timedelta(time=int1)
        return(starter + time_ahead)
# Remember, you can't set "years" on a timedelta!
# Consider a year to be 365 days.

## Example
# time_machine(5, "minutes") => datetime(2015, 10, 21, 16, 34)

:point_right: When passing arguments by keyword, the keyword must be literal.

On this line, "time" is a variable that contains the keyword:

        time_ahead = datetime.timedelta(time=int1)

But "time" is not itself a keyword of a timedelta argument. You might need a chain of elseif to be sure the proper argument is being passed.
