如何从Python列表中删除重复项并保持顺序?
问题描述:
给出一个字符串列表,我想按字母顺序对它进行排序并删除重复项.我知道我可以做到:
Given a list of strings, I want to sort it alphabetically and remove duplicates. I know I can do this:
from sets import Set
[...]
myHash = Set(myList)
但是我不知道如何按字母顺序从哈希中检索列表成员.
but I don't know how to retrieve the list members from the hash in alphabetical order.
我还没有嫁给哈希,因此任何实现此目的的方法都行得通.另外,性能也不是问题,所以我宁愿选择一种在代码中清楚表达的解决方案,而不是一种快速但不透明的解决方案.
I'm not married to the hash, so any way to accomplish this will work. Also, performance is not an issue, so I'd prefer a solution that is expressed in code clearly to a fast but more opaque one.
