Python为字典项添加值

Question

我有一本下面这样的字典。你知道吗

inventory = {
    'gold' : 500,
    'pouch' : ['flint', 'twine', 'gemstone'], # Assigned a new list to 'pouch' key
    'backpack' : ['xylophone','dagger', 'bedroll','bread loaf']
}

如何在“gold”键下存储的数字上加50？你知道吗

Answer 1

inventory['gold']将获得'gold'键的值。所以如果你想给这个值加50，只需写inventory['gold'] += 50。你知道吗

Answer 2

如评论所述：

inventory['gold'] += 50
