Re: Django Rest Framework Output as list of lists

[GMail]

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)
