Class matrix novice question

[John_paul]

Hello,


Part of my homework:

The attribute self.ground is the matrix who represents the ground of the game, it is a list of lists of integers, of dimensions self.height lines and self.width columns. The initial values are -2 in the first four lines and -1 on the rest of the ground. A negative value show that the case is empty

I don't see at all what i must write.

It doesn't look like you've provided enough information here.

width=10
height=8

# You can create the lines like this
# lineOfMinusTwo=[-2]*width
# lineOfMinusOne=[-1]*width

# So:

ground=[] # Start with empty
# lines of -2 for the first 4
for _ in range(4):
    ground.append([-2]*width)
# lines of -1 for the rest
for _ in range(4,height):
    ground.append([-1]*width)

When you are a tattooed python programmer who wants to show off your one-liner mad skillz, the same thing can be done with:

ground=[[[-1,-2][i<4]]*width for i in range(height)]

Ok thank you.
