how to extend the numpy array in loop

Question

import numpy as np

attendance = np.array([1,0,0,1,1,1,0,1,0,1,1,1,1,1,1,1,1,1,1,1,0,1,0,0,1,1,1,1,1,1,1,0,1,1,1,1,0,0,0,1,1,1,1,1,1,1,1,1,1,1,1,0,0,0,0,0,1,1,1,1,1,1,1,0,0,0,1,1,1,1])

name_list = np.array(["Ali","Ahmad","Beng","Chris","Sita","Marion","Stephen","Cobby","Akmal","Nita"])

day_list = np.array(["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"])

attendance=np.reshape(attendance,[10,7])

an the output for attendance for a week

 array([[1, 0, 0, 1, 1, 1, 0],
       [1, 0, 1, 1, 1, 1, 1],
        [1, 1, 1, 1, 1, 1, 0],
        [1, 0, 0, 1, 1, 1, 1],
        [1, 1, 1, 0, 1, 1, 1],
        [1, 0, 0, 0, 1, 1, 1],
        [1, 1, 1, 1, 1, 1, 1],
        [1, 1, 0, 0, 0, 0, 0],
        [1, 1, 1, 1, 1, 1, 1],
        [0, 0, 0, 1, 1, 1, 1]])

i want to append each name in name_list to most-left in each item in attendance

Answer 1

Try this

C = np.concatenate((name_list.reshape(-1,1),attendance), axis=1)
print(C)

Output
