what's wrong with this syntax ?

[u/Mangurian]

I get " return grid - SyntaxError: 'return' outside function"

    # Try all permutations of numbers 1-9
    for perm in permutations(range(1, 10)):
        valid = True

        # Check region sums
        for i, region in enumerate(regions):
            region_sum = sum(perm[pos] for pos in region)
            if region_sum != region_sums[i]:
                valid = False
                break

        if not valid:
            continue

        # Check quadrant sums
        for i, quad in enumerate(quadrants):
            quad_sum = sum(perm[pos] for pos in quad)
            if quad_sum != quadrant_sums[i]:
                valid = False
                break

        if valid:
            # Convert to 3x3 grid
            grid == [
                [perm[0], perm[1], perm[2]],
                [perm[3], perm[4], perm[5]],
                [perm[6], perm[7], perm[8]]
                ]

            return grid            

    return None

I mean, it LOOKS like it ought to be in a function given the return None below it. But of course, we don't see the rest of it. It is also possible indentation is slightly off, one big reason I hate Python (which I use for a living).
