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)

You can use np.tile() to append multiple times along a certain axis.

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