"can't multiply sequence by non-int of type 'list' " python 错误 3

Question

在以下代码中 A 初始化后，我一直收到错误 "only 2 non-keyword arguments accepted"。有人可以告诉我出了什么问题或我应该如何解决这个问题吗？这是我用来定义函数的代码：

import numpy as np

A = np.array([10.0, 11.0, 15.0, 17.0, 12.0, 15.0, 18.0, 34.0, 14.0, 12.0, 19.0, 15.0],

def bonus(A,B):
    A = np.array([10.0, 11.0, 15.0, 17.0, 12.0, 15.0, 18.0, 34.0, 14.0, 12.0, 19.0, 15.0],

    C = (A*B)
    return(C)

bonus(A,B)

Answer 1

您忘记在 A 的开头和结尾添加额外的括号。应该是：

A = np.array([[10.0, 11.0, 15.0, 17.0, 12.0, 15.0, 18.0, 34.0, 14.0, 12.0, 19.0, 15.0],

             [20.0, 20.0, 21.0, 23.0, 27.0, 22.0, 25.0, 21.0, 24.0, 25.0, 26.0, 27.0],
             [20.0, 20.0, 21.0, 23.0, 27.0, 22.0, 25.0, 31.0, 24.0, 25.0, 26.0, 27.0],
             [20.0, 20.0, 21.0, 23.0, 27.0, 22.0, 25.0, 21.0, 24.0, 25.0, 26.0, 27.0],
             [20.0, 20.0, 21.0, 23.0, 27.0, 22.0, 25.0, 21.0, 20.0, 25.0, 26.0, 27.0],
             [20.0, 20.0, 21.0, 23.0, 27.0, 22.0, 25.0, 21.0, 20.0, 25.0, 26.0, 27.0],
             [20.0, 20.0, 20.0, 23.0, 27.0, 22.0, 25.0, 21.0, 24.0, 25.0, 26.0, 27.0],
