如何使用for循环将字符串附加到数组中的特定位置

Question

I am new to python and Linux. I found a problem while trying append strings to a specific position in an array with a for loop.
This is simplied description of my work.

This is my input file1:
a,b,c,d,e,f

Input file2:
name1,a,b,d,e
name2,b,e,f

I would like to get the output file that the same letter will be in the same column as shown below:

  a,b,c,d,e,f
  name1,a,b,0,d,e,0
  name2,0,b,0,0,e,f

I search for Linux scripts but so far I could not found the suitable one. Then, I tried with NumPy array in python but there is only np.insert or np.append function but they seem to not appropriate for my situation.
Following is the python script that I processed

    import numpy as np
    header = np.loadtxt("file1.txt", dtype= str, delimiter=',')
    lines = np.loadtxt("file2.txt", dtype= str, delimiter=',')
    ARG = np.empty([2,7], dtype=str)
    for x, line in enumerate(lines):
       for i in line:
          for y, j in enumerate(header):
             if i == j:
               np.insert(ARG, y, i, axis=x)
               print(ARG)
             else:
               np.insert(ARG, y, 0, axis=x)
    np.savetxt('test.csv', ARG, delimiter=',')

The output shows an error like IndexError: index 3 is out of bounds for axis 0 with size 2, and the added strings were not at the correct position in the array. Would you mind giving me some suggestions?
Thank you.

Try this. insert function does the work here:

my_list1 = ['name1','a','b','d','e']
my_list2 = ['name2','b','e','f']

my_list1.insert(3,0)
my_list1.insert(7,0)

my_list2.insert(1,0)
my_list2.insert(4,0)
my_list2.insert(5,0)
print(my_list1)
print(my_list2)

output:

['name1', 'a', 'b', 0, 'd', 'e', 0]
['name2', 0, 'b', 'e', 0, 0, 'f']
