Extract dict value from list of dict? [duplicate]

Answer 1

You can use a list comprehension:

ids = [y['id'] for y in x]

This assumes that every dictionary has a key 'id'. If you're not sure that key exists in every dictionary, you can use this one:

ids = [y['id'] for y in x if 'id' in y]

Answer 2

You can use itemgetter from operator:

y = list(map(itemgetter('id'), x))

Answer 3

I think you want:

[a["id"] for a in x]
