For loop with append and array issue

Question

How to make append multiple times in for loop to get same results for B like below

import numpy as np

B1 = np.linspace(0,1,7)
B2 = np.linspace(3,8,7)

B = np.append(B1, B2)

B = np.append(B, B2)
B = np.append(B, B2)
B = np.append(B, B2)
B = np.append(B, B2)

so far try something like this but i don't have anny ideas

n = 5 
for i in range(n):
    B[i] = np.append(B, B2) 

Answer 1

您可以使用np.tile（）沿某个轴附加多次。

B = np.append( B1, np.tile(B2, (1, 5)) )

Answer 2

n = 5 
for i in range(n):
    B = np.append(B, B2)
