list - Python - sum values in dictionary

I have got pretty simple list:

example_list = [
    {'points': 400, 'gold': 2480},
    {'points': 100, 'gold': 610},
    {'points': 100, 'gold': 620},
    {'points': 100, 'gold': 620}
]

How can I sum all gold values? I'm looking for nice oneliner.

Now I'm using this code (but it's not the best solution):

total_gold = 0
for item in example_list:
    total_gold += example_list["gold"]
