How to add elements of another list to a list?

Question

Python

Good afternoon everyone. There are 2 lists. How can I put another list into one list, but only one element at a time?

sp_with_follow = ['one', 'two', 'three', 'four', 'five']
res_list = ['1', 2, '3', 4, 5]
for i in range(len(sp_with_follow)):
    for cv in sp_with_follow:
        res_list.insert(4, cv)
print(res_list)

Conclusion:

['1', 2, '3', 4, 'five', 'four', 'three', 'two', 'one', 'five', 'four', 'three', 'two', 'one', 'five', 'four', 'three', 'two', 'one', 'five', 'four', 'three', 'two', 'one', 'five', 'four', 'three', 'two', 'one', 5]

But how to get the output

['1', 2, '3', 4, 'one', 5, '1', 2, '3', 4, 'two', 5, '1', 2, '3', 4, 'three', 5, '1', 2, '3', 4, 'four', 5, '1', 2, '3', 4, 'five', 5]

Answer 1

sp_with_follow = ['one', 'two', 'three', 'four', 'five']
res_list = ['1', 2, '3', 4, 5]
out = []

for el in sp_with_follow:
    res_copy = res_list[:]
    res_copy.insert(4,el)
    out.extend(res_copy)

print(out)

OUT

['1', 2, '3', 4, 'one', 5, '1', 2, '3', 4, 'two', 5, '1', 2, '3', 4, 'three', 5, '1', 2, '3', 4, 'four', 5, '1', 2, '3', 4, 'five', 5]
