No numerals, code coach

Question

I have been trying to solve the no numerals code coach problem using python. This is the code i cameup with but it doesn't work. I cant figure out why. Will someone help? I dont need the solution for the problem. I just need an explanation as to why it wont work. Im a beginner with python btw

s=input()
nums=["zero","one","two","three","four","five","six","seven","eight","nine","ten"]
for i in range(11):
s.replace(str(i),nums[i])

print(s)

Answer 1

You need to restore your new string in s.

s = s.replace(str(i),nums[i])

There is one more problem after that:

Try to run your code with 10 and see what happens. 😉

Answer 2

A String is immutable.
So replace() returns another String and s keeps the same.
Assign the return of replace to s.
