this solution should not pass

My code passed the first 5 testcases, then it failes.

is the testing correct??
Since 86% of 58 warriors solved it, I guess my code is the problem.

Sorry, but that actually still doesn't make sense.

The current task is to retroengineer the specs that aren't given. That's generally a bad idea for a kata.

After a tile is placed, it should organically connect to other neighboring tiles. In the example, purple color represents the edge of a tile (and the shape that will be formed), whereas red represents the main part of the tile.

1. I don't see any purple (maybe my screen?)
2. you use notions that aren't defined/demonstrated: what is the main part of the tile? the edge?

If I take the picture, I'd assume that 1 should match the tile at the center of this:

...
.XX
.XX

which doesn't match the 1 in the exmaple of grid at the end of the description

=> ?

You have to explain the tools you want us to use.

Cheers

Please provide more examples in description, elaborate it a bit more.

nice kata, the only suggestion I could give is maybe don't stuck the fill_value only to None? But can be more customed? thanks

While breaking down names into several lines (like in examples 4-6), trailing spaces should not be trimmed. Remember, width of each line is 32 characters. The gap after all listed products is also a string of 32 spaces.

Cases like

80 x Whole-grain cereal bars
                         $400.00

Expects no trailing whitespaces, which is inconsistent to the handling when the product description alone spans multiple lines.

The price is always right-aligned and rounded to 2 decimal places (even if it's integer).

This will cause a loss of precision for the total amount, but the handling is not mentioned anywhere. e.g There are 3 products that each costs $10.004, their total would be $30.012, so should the total be $30.00 or $30.01?

Edit: This is already happening in the random tests. $30.01 is expected, but this is not reasonable, since that the rounded price of all products doesn't equal to the total.

The meaning of is_countable isn't explained enough. (The part about 2 x and 455g is not mentioned anywhere)

No random tests. can be hardcoded
