Stuck on challenge

I'm just wondering what I'm doing wrong here.

time_machine.py
import datetime

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

# Remember, you can't set "years" on a timedelta!
# Consider a year to be 365 days.
def time_machine(inte, stri):
    s = stri
    if s == "year":
        return starter + datetime.timedelta(vars()[s] = inte * 365)
    else:
        return starter + datetime.timedelta(vars()[s] = inte)


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

Hey Jackson Porter ! :wave:

You're very close! We can even shorten it down further here as well. I believe the issue is the string we're checking on and the vars()[] which I'm personally not familiar with.

First, we need to be checking for the string of "years" (plural) instead of "year". If it is "year", we can just re-assign the s variable's value to "days". Then we can re-assign the inte variable's value to inte = inte * 365 or inte *=365.

Then outside of that if, we can utilize the ** unpacking operator like so...

return starter + datetime.timedelta(**{s: inte})
