04_Numpy模块的使用

import numpy as np
data1 = np.array([2,3,5])
data2 = np.array([[25,56],
                  [665,8]])
data3 = np.zeros([5,6])
data4 = np.ones([5,2])
data3[0,0] = 5
print(data1)
print(data2)
print(data1.shape)
print(data2.shape)
print(data3)
print(data4[1,1])
#矩阵的运算
import numpy as np
data1 = np.ones([2,3])
data2 = np.array([[2,5,6],
                 [5,8,6]])
print(data1*5)
print(data1+data2)
print(data1*data2)
