There have been quite a few issues because of whitespaces. Lots of people solved the kata, so please recheck your solution for whitespaces at the beginning or end of your return String...

you have to check your types on your own. do you have them as Strings??
or are you missing an import?
maybe repl.it has default imports that cover the methods you use.

Please try again, lots of people solved it so this does not seem to be a code issue of the kata...

It seems a lot of people are having whitespace issues... please check your code. It should definately work

it should work. As Seonnyn said, check your whitespaces...

Can anyone contribute and add Python testcases with random test?

There is a testcase that has a word that starts with a number.

which language?

Changed the description!
Please check.

Are you sure that there are no additional whitespaces in your solution?
Anyone else with the same problem??

Not sure if this is a reason for an issue unless the problem is in the testcases...

Yes it is. See comments above.

Done!!

which language??

sorry that I've been gone so long...
