删除字典中的几个列表项 [英] Deleting a few list items inside of dictionary
问题描述
删除字典内的几个列表项目
我有一个字典:
phone = {first:100,second:200,third:[10,12,5,38],fourth:400}
让我们想从手机字典中删除12和5。
有没有办法使用del功能?
我知道如何使用.remove()
手机[第三]删除(12)
手机[第三]删除(5)
但我想知道是否可以使用del()?
谢谢。
编辑:对于所有那些专注于del使用索引,删除使用确切值的回复,我正在重新定义我的问题: p>
我想删除表示手机字典中第三个键值项的列表中的索引1和2。我该怎么做?
解决方案你必须通过索引而不是价值来做到这一点:
>>> phone = {first:100,second:200,third:[10,12,5,38],fourth:400}
>>> del(phone [third] [1:3])
>>>电话
{'second':200,'fourth':400,'third':[10,38],'first':100}
删除列表中位置1和2中的元素。
Deleting a few list items inside of dictionary
Hi,
I have a dictionary:
phone = {"first":100,"second":200,"third":[10,12,5,38],"fourth":400}
Let' say I want to remove the 12 and 5 from from "phone" dictionary.
Is there a way to do that using a "del" function?
I know how to do this, using a .remove()
phone["third"].remove(12)
phone["third"].remove(5)
but I was wondering if it is possible to do it using the del()?
Thank you.
EDIT: For all those replies concentrating on "del uses index, remove uses the exact value", I am redefining my question:
I want to delete the indexes 1 and 2 in the list representing the third key-value item in "phone" dictionary. How can I do that?
解决方案 You have to do this by index rather than value:
>>> phone = {"first":100,"second":200,"third":[10,12,5,38],"fourth":400}
>>> del(phone["third"][1:3])
>>> phone
{'second': 200, 'fourth': 400, 'third': [10, 38], 'first': 100}
This deletes elements in position 1 and 2 in the list.
