list.reverse() 和 list.sort() 分别表示原地倒转列表和排序(注意,元组没有内置的这两个函数)。 reversed() 和 sorted() 同样表示对列表 / 元组进行倒转和排序,reversed() 返回一个倒转后的迭代器;sorted() 返回排好序的新列表。 字典和集合 字典是一系列由键(key)和值(value)配对组成的元素的集合。相比于...
List methods are all void; they modify the list and return None.If you accidentally write t = t.sort(), you will be disappointed with the result. 10.7 Map, filter and reduce To add up all the numbers in a list, you can use a loop like this: ...
