Complete the code to implement the following operations:

1. 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.
2. Call read_date() to read four (unique) date objects and store the date objects in a list.
3. Call sorted() to sort the list of date objects, earliest first. Store the sorted dates in a new list.
4. Output the sorted_dates, in the format mm/dd/yy.
   • Hint: Use strftime() to format the date outputs. (See resource below.)
5. Output the number of days between the last two dates in the sorted list as a positive number.
6. 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.
7. Output the full name of the day of the week of the earliest day.

Code I have so far:

from datetime import date,timedelta

def read_date():
    inputDate=input()
    listDate=inputDate.split("-")
    x = date(int(listDate[0]),int(listDate[1]),int(listDate[2]))
    return x

DateObject=[]
print()
for i in range(4):
    DateObject.append(read_date())
    
DateObject.sort()
print()
for i in DateObject:
    print(i.strftime("%m/%d/%Y"))
    
print((DateObject[3]-DateObject[2]).days)
d = timedelta(days=21)
t= DateObject[-1]+d
print(t.strftime("%B %d, %Y"))
print(DateObject[0].strftime("%A"))

error I am getting:

it says that for all of my outputs I have two lines before the text in my output:
