Re: Django Rest Framework Output as list of lists

Hi!

Seems like more StackOverflow question to me, since it has nothing to do with Django. But anyway, you could use list comprehensions:

    >>> result = [[x['date'], x['price']] for x in source['navs']]

Also, it looks like list of lists is overkill (list uses more memory than tupple), and if you don't plan to change inner lists, it would be better to do that:

    >>> result = [(x['date'], x['price']) for x in source['navs']]

Furthermore, it may be a good idea to use namedtuples here, it could help readability:

    >>> from collections import namedtuple

    >>> PriceOfTheDay = namedtuple('PriceOfTheDay', ('date', 'price'))

    >>> result = [PriceOfTheDay(x['date'], x['price']) for x in source['navs']]

...and after that you could access date and price via PriceOfTheDay attributes:

    >>> print(result[0].date, result[0].price)
