Getting invalid argument

I am getting invalid argument

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.

## Example
# time_machine(5, "minutes") => datetime(2015, 10, 21, 16, 34)
def time_machine(in_int,in_str):
    if in_str=="years":
           return starter+datetime.timedelta(days=365*in_int)
    else:
            return starter+datetime.timedelta(in_str=in_int)

So the function doesn't like seeing a variable where it expects a keyword. But you did a good job handling the "years" case. :+1:

:point_right: What if you created an elif chain to test the other possible keywords, and then used each of them explicitly like you did for "years"?
