Can't find my error - Python

Question

I'm trying to solve a challenge. The code should replace digits in a string with respective words, eg. 'there are 5 cups' to 'there are five cups'. It fails one of the tests and I can't figure out why.
I know it's a crude code, but I think it should work.

Answer 5

BroFar yeah I fixed it in the challenge but forgot to change one line in the code that I linked to. Now it's ok here as well. I guess I have to work on my punctuality :-)

Answer 6

Pavel 👌👍

Answer 7

BroFar I really believe I did. I replace 10 first and then replace 1 and 0 after that, so there should be no problem.
