python - generate list from values of certain field in list of objects -


how generate list of values of field of objects in list?

given list of objects:

[ {name: "joe", group: 1}, {name: "kirk", group: 2}, {name: "bob", group: 1}]

i want generate list of name field values:

["joe", "kirk", "bob"]

the built-in filter() function seems come close, return entire objects themselves.

i'd clean, 1 line solution such as:

filterlikefunc(function(obj){return obj.name}, mylist)

sorry, know that's c syntax.

using list comprehension approach get:

objects = [{'group': 1, 'name': 'joe'}, {'group': 2, 'name': 'kirk'}, {'group': 1, 'name': 'bob'}] names = [i["name"] in objects]

for intro list comprehensions, see https://docs.python.org/2/tutorial/datastructures.html
