from datetime import date, timedelta

def all_sundays(year):
# January 1st of the given year
    dt = date(year, 1, 1)
# First Sunday of the given year       
    dt += timedelta(days = 6 - dt.weekday())  
    while dt.year == year:
        yield dt
        dt += timedelta(days = 7)

for s in all_sundays(2020):
print(s)
