推荐答案

使用 key 指定一个参数的函数，该参数用于从每个列表元素中提取比较键.参数 reverse 是一个布尔值.如果设置为True，则对列表元素进行排序，就好像每个比较都被撤消一样.

Use key to specify a function of one argument that is used to extract a comparison key from each list element. The argument reverse is a boolean value. If set to True, then the list elements are sorted as if each comparison were reversed.

>>> l = [['Alfred Jeffries', '9'], ['Peter Smalls', '10'], ['Bob Daniels', '8']]
>>> sorted(l, key=lambda x: int(x[1]), reverse=True)
[['Peter Smalls', '10'], ['Alfred Jeffries', '9'], ['Bob Daniels', '8']]
