#适用条件：列表元素都是正整数 from numpy import * import numpy as np #v_list = [2,1,2,3,1] v_list = [3,1,2] print('v_list is : ',v_list) # 若 v_list[i] = k ， 则 v_element_cnt_list[k] +=1 ## 即 v_element_cnt_list[k]记

from functools import * import functools as ft from numpy import * import numpy as np v_list = [3,62,1,93,75,82,13,62,5,51] v_list_len = len(v_list) print('原列表 ：',v_list,'\n') #使用 mean()计算平均数 v_mea

#使用 sort() v_list = [3,62,1,93,75,82,13,62,5,51] v_list_len = len(v_list) print('原列表 ：',v_list,'\n') v_list_sort = v_list.sort() print('排序结果 ：',v_list_sort,'\n') #冒泡排序 v_list = [3,62,1,93,75,82

Python--矩阵

multiply 1、 数组对应元素相乘 from numpy import * import numpy as np A = np.array([[1, 2, 3], [4, 5, 6]]) E = np.array([[10, 20, 30], [40, 50, 60]]) D = np.multiply(A,E) print(type(D)) print(D,’\n’) B
