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


Guys, I'm in that point where I did it a million times and I probably started making it worse without noticing it. Can anybody help me here?

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(duration, unit):
    if unit == 'minutes':
        offset = datetime.timedelta(minutes = duration)
    elif unit == 'hours':
        offset = datetime.timedelta(hours = duration)
    elif unit == 'years':
        offset = datetime.timedelta(days = duration * 360)
        return starter + offset

You are very close! I see the following errors:

  • missing option for "days" units
  • year has 365 days not 360
  • no default value for offset which causes a "reference before assignment error

Post back if you need more help. Good Luck!!

Thanks !!!
