Hey mate, this is not an issue with the kata.

You need to ensure that your digits match those specified in the description precisely.

maybe it sounds weird, but I ran my prog on IDLE and everything is OK, however here I didn't pass any test

I see what you mean; myjinxin's is indeed more difficult. Marking issue resolved.

errr... I'd tend to somewhat disagree about the one you linked, since in myjixin's kata, the size is varying while it's not the case here. So the present one is clearly an easier version of the other, but not really a duplicate, imo (the simplest way to solve the present one will never solve the other, for instance)

(but again, there might exist an "unfindable" python kata which would make the present beta an exact ducplicate...)

It's a good kata, but unfortunately been done before. Resolving question as it's actually an issue.

It's a decent kata, but unfortunately a duplicate: https://www.codewars.com/kata/59cc4c5aaeb284b9a1000089

Didn't find that one when I went digging around for similar Kata sadly.
I did find: https://www.codewars.com/kata/52a7099f8a4d9604bb000472 (which is focused around printing the 7bit number that lights the individual segments.)

I believe there is another in python (I already solved something like that)

A very similar kata: https://www.codewars.com/kata/59cc4c5aaeb284b9a1000089

Resolved

Added examples of all combinations.

Yep, that was an oversight on my end. Fixed it.

Sample tests cannot be run.

The shape of each digit should be in the description, not only in the sample tests.
