问题描述
我有一个很简单的列表:
example_list = [
{'points':400,'gold ':2480},
{'points':100,'gold':610},
{'points':100,'gold':620},
{'points' 100,'gold':620}
]
金值?现在我正在使用这个代码(但不是最好的解决方案):
total_gold = 0
/ pre>
在example_list中的项目:
total_gold + = example_list [gold]
解决方案sum(item ['gold'] for myLIst中的项目)
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"]
解决方案sum(item['gold'] for item in myLIst)
