There is no need in print(text) and you can just use "replace" without "find". Good luck!

It's amazing how such solutions get at the top of the rating? What's the secret? :)

The secret is to have more likes than others ;)

That's a clever solution, but still it could be completed without using while or str.find() method, for example through using functional methods like map, filter and reduce. Still, it's a good solution.

Thank you for sharing! This is a really good to read, educational solution.

what`s the aim for import string ? IMHO it would be clearer if you have written text.replace('right', 'left') instead of phrases and then while would not be needed

Interesting solution but you can remove the while A for loop would be more clear and readable

you don't need the while condition here - first you put all phrases into one string. The text.replace will replace all occurances of 'right' in text, so after the first run there won't be any more 'right' in the text.

List but not the least
