Returns the n maximum elements from the provided list.
If n is greater than or equal to the provided list’s length, then return the original list (sorted in descending order).
Use sorted() to sort the list, [:n] to get the specified number of elements.
Omit the second argument, n, to get a one-element list.
代码实现
def max_n(lst, n=1):
return sorted(lst, reverse=True)[:n]使用样例
max_n([1, 2, 3]) # [3]
max_n([1, 2, 3], 2) # [3,2]
