找出numpy数组中最大的N个数的索引: deffindTopNindex(arr,N):returnnp.argsort(a)[::-1][:N] 测试: test = np.array([2,5,6,3,4,6,4,8,6,5])print(findTopNindex(test,3)) >[7 8 5 2]
def double_list_elements(lst): return [i * 2 for i in lst] 题目要求将列表中所有元素乘以2。给定的函数`double_list_elements`使用列表推导式遍历输入列表`lst`中的每个元素`i`,然后对每个元素执行`i*2`操作,最后将结果放入新列表中返回。列表推导式的写法`[i*2 for i in lst]`直接且高效,完全满足...
