Django turn lists into one list

Hello i want to put this data into one list so i can sort it by timestamp. I tried itertools chain but that didn't really work. Thank you for your help :)
`

for i in user:
    name.append(i['name'])

for i in next_level:
    rating_values.append(i['rating'])

for i in comment_values:
    comments_count.append(i['count'])

for i in likes_values:
    likes_count.append(i['count'])

for s in rating_values:
    ratings.append(s['value'])

for s in date:
    ratings.append(s['date'])   




ab = itertools.chain([name], [rating_values], [comments_count], [likes_values], [comment_values], [date])
list(ab)
