Trying to create a checkerboard with alternating white and black squares. This code keeps coming up with an error and cannot find the solution or how to have the code appear on the canvas.
the error code is "mismatched input 'n' expecting COLON
x = 10
y = 10
sq_size = 20
def setup ():
background (150)
for i in range(8):
for n in range(8):
fill (255)
if i + n % 2 == 0
else:
fill (0)
rect(x + i * sq_size, y + n *sq_size, sq_size, sq_size)
python processing

@MaximeBelseis valid after aforloop -- it means "if the loop ran to completion and did not break early, run this code". (Granted, it seems like that is not what the questioner intended here.)

That if statement is in the wrong place. Try something like this:
x = 10
y = 10
sq_size = 20
def setup ():
size(200,200)
background (150)
def draw():
for i in range(8):
for n in range(8):
if (i + n) % 2 == 0:
fill (255)
else:
fill (0)
rect(x + i * sq_size, y + n *sq_size, sq_size, sq_size)
