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

I am stuck here can someone kindly help me

time_machine did not return right date

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(integer, string):
  if string == 'hours' :
    return starter + datetime.timedelta(hours = integer)
  elif string == 'days' :
    return starter + datetime.timedelta(days = integer)
  elif string == 'year' :
    return starter + datetime.timedelta(year = integer*365 * 9)
  elif string == 'minutes' :
    return starter + datetime.timedelta(minutes = integer)


time_machine(3,'days')

The year part is messing you up.

# Remember, you can't set "years" on a timedelta!

The expected argument for year is 'years' not 'year'

elif string == 'years' :

The unit conversion and keyword argument is wrong.

x * 365 * 9 does not land you anywhere near year.

timedelta does not support years so you need to convert it. In this case, shortest one is days = integer * 365

return starter + datetime.timedelta(days = integer * 365)

Solved.
