timedelta question

please how can I fix my code so that a Timedelta could be constructed from time_machine arguments and add it to starter.

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(a,"days"):
  x = datetime.timedelta(a)
  return starter + x

Hello, your full code to this challenge should look like this:

import datetime

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

def time_machine(integer, string1):
  if string1 == 'hours':
      return starter + datetime.timedelta(hours=integer)
  elif string1 == 'days':
      return starter + datetime.timedelta(days=integer)
  elif string1 == 'minutes':
      return starter + datetime.timedelta(minutes=integer)
  elif string1 == 'years':
      return starter + datetime.timedelta(days=integer*365)

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

time_machine(3, 'days')

Hello Devin.

could you please explain your code a little?

Your code looks beautiful and I am pretty sure it is good for the code challenge (I haven't even tested it), but we would much prefer some explanations on the forums.

Also, it turns out that good programmers are lazy, so we just don't want the to copy and paste some else's solutions! :D

Thanks for your help!

Vittorio
