Convert datetime generator object to list of date strings

Question

I have a list of DateTime object in a generator

l = [datetime.date(2016, 1, 7), datetime.date(2016, 1, 14), datetime.date(2016, 1, 21), datetime.date(2016, 1, 28), datetime.date(2016, 2, 4)]

How can we convert that into a list of date strings format?

output :

['2016-01-07', '2016-01-21', '2016-01-28', '2016-03-04']

The `datetime` documentation shows you how to format a `datetime` value to a string of your choosing. `apply` that to the list. Where are you stuck with the process? — Prune, Jun 08 '21 at 17:21

The question is not repeated, it's different and I have added it because many beginners need such basics. If the question asked, doesn't mean that, one should compare the question with points. It might have been for everyone especially beginners. — sam, Jun 08 '21 at 17:27

using datetime.strftime

import datetime
l = [datetime.date(2016, 1, 7), datetime.date(2016, 1, 14), datetime.date(2016, 1, 21), datetime.date(2016, 1, 28), datetime.date(2016, 2, 4)]
date_string = [d.strftime('%m-%d-%y') for d in l]
print(date_string)

You can use map and get the required output as follows:

import datetime
l = [datetime.date(2016, 1, 7), datetime.date(2016, 1, 14), datetime.date(2016, 1, 21), datetime.date(2016, 1, 28), datetime.date(2016, 2, 4)]
output = list(map(lambda x:x.strftime('%Y-%m-%d'),l))
print(output)
# ['2016-01-07', '2016-01-21', '2016-01-28', '2016-03-04']
