11.11 LAB: Dates Complete the code to implement the following operations: Complete read_date(): Read an input string representing a date in the format yyyy-mm-dd. Create a date object from the input string. Return the date object. Call read_date() to read four (unique) date objects and store the date objects in a list. Call sorted() to sort the list of date objects, earliest first. Store the sorted dates in a new list. Output the sorted_dates, in the format mm/dd/yy. Hint: Use strftime() to format the date outputs. (See resource below.) Output the number of days between the last two dates in the sorted list as a positive number. Output the date that is 3 weeks from the most recent date in the format "July 4, 1776". Hint: Use timedelta() to set a duration of time for the arithmetic on date objects. (See resources below.) Ex: timedelta(days=50, seconds=27, hours=8, weeks=2) will define a duration of 50 days + 27 seconds + 8 hours + 2 weeks. Output the full name of the day of the week of the earliest day. Ex: If the input is: 2022-01-27 2022-07-04 2020-12-31 2022-07-29 the output is: 12/31/2020 01/27/2022 07/04/2022 07/29/2022 25 August 19, 2022 Thursday

11.11 LAB: Dates
Complete the code to implement the following operations:
- Complete read_date():
- Read an input string representing a date in the format yyyy-mm-dd.
- Create a date object from the input string.
- Return the date object.
- Call read_date() to read four (unique) date objects and store the date objects in a list.
- Call sorted() to sort the list of date objects, earliest first. Store the sorted dates in a new list.
- Output the sorted_dates, in the format mm/dd/yy.
- Hint: Use strftime() to format the date outputs. (See resource below.)
- Output the number of days between the last two dates in the sorted list as a positive number.
- Output the date that is 3 weeks from the most recent date in the format "July 4, 1776".
- Hint: Use timedelta() to set a duration of time for the arithmetic on date objects. (See resources below.)
Ex: timedelta(days=50, seconds=27, hours=8, weeks=2) will define a duration of 50 days + 27 seconds + 8 hours + 2 weeks.
- Hint: Use timedelta() to set a duration of time for the arithmetic on date objects. (See resources below.)
- Output the full name of the day of the week of the earliest day.
Ex: If the input is:
2022-01-272022-07-04
2020-12-31
2022-07-29
the output is:
