Insert from one list into another in python

Question

I'm trying to insert from one list into another in python but i cant seem to get it working. I would like to insert the first line of list2 under the first line in list1 that contains 'A1033', then at the next line in list1 that contains 'A1033' insert the second line of list2 and so on. this is the code that i have:

with open('D:\TranslateFIles\Ext_Python.txt', 'r', encoding='utf-8') as f:
    list1 = f.readlines()
f.close()

with open('D:\TranslateFIles\A1033_Python.txt', 'r', encoding='utf-8') as f:
    list2 = f.readlines()
f.close()

outFile=open('D:\TranslateFIles\Output3_Python.txt', 'w', encoding='utf-8')

A1033 = 'A1033'
a2067 = 'A2067'

 
for line in list1:
    for line2 in list1:
        for element in list2:
            if A1033 in line:
                if not a2067 in line2:
                    list1.insert(list1.index(line2), element)
                    
            
for lines in list1:
    outFile.write(lines)
outFile.close()

Answer 1

Suppose l1 and l2 are you first two list and output is your result then

output = []
for i in l1:
    output.append(i)
    if 'A1033' in i:
        output.append(l2.pop(0))
