List comprehention with 2 variable

Question

Is there any way to use list comprehension in this case ?

l=[]
for i in range(-1,2):
    for j in range(-1,2):
        l.append([i,j])

Output:

[[-1, -1], [-1, 0], [-1, 1], [0, -1], [0, 0], [0, 1], [1, -1], [1, 0], [1, 1]]

Answer 1

You can use:

l = [[i, j] for i in range(-1, 2) for j in range(-1, 2)]

Result:

# print(l)
[[-1, -1], [-1, 0], [-1, 1], [0, -1], [0, 0], [0, 1], [1, -1], [1, 0], [1, 1]]
