这是我的numpy数组：
ls = [[1,2,3], [3,4] , [5] , [7,8], [23], [90, 81]]
我需要将数组第二行中的值乘以array([[ 1, 0, 4, 3],
[ 10, 100, 1000, 10000]])
中列表的长度，该列表位于相应数字的索引处在第一行：
ls和10 * len(ls[1])等。
目标输出将是以下数组：
100 * len(ls[0])有什么有效的方法吗？
答案 0 :(得分：3)
使用keyword2来找到长度，并将其与数组的第二行相乘为：
list comprehesion编辑：
ls = [[1,2,3], [3,4] , [5] , [7,8]]
arr = np.array([[ 1, 0, 2, 3],
[ 10, 100, 1000, 10000]])
arr[1,:] = arr[1,:]*([len(l) for l in ls])
arr
array([[ 1, 0, 2, 3],
[ 30, 200, 1000, 20000]])
