Answer 1

Error is
list append() method does not return anything.. It reflect on original list. So
final.append("10") modify final list. Return none. So assigning to final = final.append("10") makes final list none. Just use
final.append("10")

But this code , just splitting to list only..
What is your logic?

Answer 2

Im still a begginer at coding and so its all i know, what is the better way?

Answer 3

Just go on your logic first then go for optimize.
Iam not understood your logic so i cant suggest more on that.
But only say that input is text with like sample
abc 0 1 9 10 ef
Here, your for loop take charecter by charecter, you can change 0 - 9 but not 10. text[i] == 10 never true, because it wont take 10, it take '1' next '0'.
Hope you understood, list.append() work.

I would do like, take input and split with space..
Next in list , values 0 to 10 if any, just replace with text. This can be done in many ways.. Use of a dictionary will simplifies code.
