A simple level generator

Let’s implement a very straightforward level generator. The following program should print an empty 10 x 10 box.

Put the lines in the correct order and run the code.

border = wall * 10
center = wall + floor * 8 + wall
border += "\n"
print(level)
center += "\n"
wall + floor * 8 + wall
floor = "."
level = border + center * 8 + border
wall = "#"
