fixed it. Still the way tests are difined in this kata is not helpful to newbie

there are over 2K python solves and the tests are fine. solving the code is not actually about printing, perhaps reread the description page?

'Value is not what was expected' while it the code is does what is asked to (i printed output to console to manually check).
something is NOK with test cases

Ah, fair enough. You can also comment on the solution itself btw.

It works fine in both versions. What kind of conversion are you talking about? Also, I don't think you need to use spoiler flag for this.

nope, read the end of the description again.

print the input to the console

If there is only one solution, you should return jist that list, not a list of lists (that part of the kata wasn't designed too well, but it's too late to change without invalidating current solutions. Maybe it's worth it to change it?)

Fixed
