python:

• new test frameworks to be used.
• running test suite generate warnings.

This issue is covered here. Closing this one.

Great kata of the chess series, a classic.

Thanks for this kata.

Amazing Kata, thx!

Don't use the Binet's formula, or floating point numbers in general, when dealing with big integers. There's no way to stop them from eventually losing precision.

Find a method for calculating the numbers which involves only integers, that way you won't lose precision.

the description could mention that the order of the output does not matter

Python:

• test framework is not properly used (missing describe/it)
• tests suite generates warnings

fork fixing both

python new test framework is required. updated in this fork

The discription mixes "space" and "whitespace" in an unclear manner.

Leading and trailing whitespace is also allowed.

yet

It should NOT match: "abc\n"

I suppose it depends on context, but from a regex perspective, I would assume "whitespace" refers to \s. I would just change everything to "spaces" for clarity.

Changed description to match the tests.

Duplicate issue

And the problem why it happens is explained in the post below yours. Closing this one.
Added the text written by dfhwze to the kata's description and a couple of examples to see what that means.

Like a previous commenter, I'm getting errors such as:

Your RegEx should NOT match ' q q'

Your RegEx should NOT match 'diii ii rr rrr zzz '

Your RegEx should NOT match 'eee ggl m o oqq qrr rrrr u'

all of which appear to satisfy the rules as stated: alphabetical order, spaces allowed.

Congratulations on creating such a challenging coding task, it really puts your dynamic programming skills to the test, keep going.
