Your English is better than my French, which is currently at the level
of "watch Let It Go with subtitles and have an approximate idea of
what she's singing". :)

In Python, "class TableauNoir:" isn't a declaration, it's an
executable statement. It's effectively the same as:

TableauNoir = type(blah blah blah)

where the "blah blah blah" part is a complete representation of the
block of code inside the class statement. When you instantiate it,
like:

foo = TableauNoir()

you create an object of that particular class. Redefining the class
later doesn't change that object, but it will mean that any new
objects you make will use the new class.

Hope that helps!
