Creating a single list with multiple instances of objects from a second list in Python

I am trying to create a list of tiles for a board game from an xml file that contains a description of the fragments. The xml file describes each type of tile and the number of tiles of this type.

So far, I have the following code that creates a list with exactly one of each tile type:

    [Tile(el.id) for el in <tile descriptions>]

I would like to create a list with the appropriate amount of each fragment, for example. something like that:

    [Tile(el.id) * <el.n_tiles> for el in <tile descriptions>]

Is there an elegant one-liner to do this, or do I need to do this for a long time, creating a list for each type of tile and then concatenating?

What about:

[Tile(el.id) for el in <tile descriptions> for _ in range(el.n_tiles)]

[Tile(el.id) for el in <tile descriptions> for i in range(<el.n_tiles>)]
