python - What is the most efficient way to group submissions based on submission.created_utc?

Question

I have a program that scans posts from a subreddit over an arbitrary length of time. With each post that is scraped, I am able to collect certain pieces of data. Ultimately, I intend to pickle the data from each day separately in order to analyze it on a separate python program.

Here is some of the relevant code:

epoch = datetime.utcfromtimestamp(0)

print('Enter scanning start time:')
now = input()
now = datetime.strptime(now, '%Y-%m-%d %H:%M:%S.%f')
sDate = now - epoch
sDate = sDate.total_seconds()

print('
Enter scanning end time:')
later = input()
later = datetime.strptime(later, '%Y-%m-%d %H:%M:%S.%f')
eDate = later - epoch
eDate = eDate.total_seconds()

for submission in subreddit.new(limit = None):
    if sDate > submission.created_utc > eDate:
        do something...

My question is: how can I best group submissions based on a date? I've still pretty new to python, and have been reading up on classes, but I am not sure if that is the best route to go. The data I am collecting can just be simply thrown together into a list. But is there an efficient way to link submission posts together based on submission.created_utc? I've already created a for loop that creates a list of date() objects that might be useful:

delta = now - later
dateRange = []

for i in range(delta.days + 1):
    dateRange.append(now - timedelta(days=i))

for i in dateRange:
    date = i.strftime('%Y-%m-%d')
    print(date)
