Classic python obfuscating every memory call.

Wouldn't it be better to first create an empty space with the required dimensions and only then fill it with the squares?
That way we could avoid this confusing situation.

Nice. May I know how you have added green block?

Instead of ["<block>"] * 5 something like "block"*5 should be used in the first example, otherwise you create a 3d array instead of the intended 2d

thats pretty confusing, why does the * 5 also not point to the same place in memory...
