you have to do it without string operation

There is a space at the end of the string, so no trailing exclamation mark -> remove them all.

Thanks, I had the exact same problem. The author definately needs to fix this.

thank you, this has gotten me much closer to passing, I am now only missing/messing up 1 piece

Thank you very much! It works now! I think the author should edit the kata description :)

Have you encountered any issues with precision of calculations? In what language?

Or you mean that there's a problem with how symbols are explained? If so, which ones?

Thank you for this - was having trouble getting the remaining amount correct, your explanation clarifies the kata description.

0 should not be counted as puncuation and should be counted as any other word

If you link your Github to your Codewars profile, your Github avatar will sync over to Codewars. :)

knock at the back door and you can edit your profile :D

Fixed.

Yes that would do it,cheers!

I think I see what you mean. Will the phrase "Consider that input is always a string" be clearer?
Or you can propose your own version of the description, so I could improve it.

Thats true description is misleading but in the examples you can see that function input can contain other characters than digits.
