Python’s built-insorted()function enables programmers to sort a list efficiently and easily. On the other hand, thelist.sort()method provides an in-place sorting mechanism. Additionally, Python allows forcustom
while thesortedreturns a new sorted list from the items in iterable. Both functions have the same options:keyandreverse. Thekeytakes a function which will be used on each value in the list being sorted to determine the resulting order. Thereverseoption can reverse the comparison order...

There’s no way to recover the original list of runners in the order they finished and find every forty-second person. In hindsight, you should’ve sorted the runners with sorted() and used the same lambda: Python >>> runners_by_duration = sorted(runners, key=lambda runner: runner....
Now remember, in Python, indexes start at zero. 因此,为了能够查看该列表的第一个元素,我需要将其放入索引0,位置0。 So for me to be able to look at the first element of that list,I need to put in index 0, position 0. 在这里,Python告诉我第一个对象,即位于...
