在存储在数组(非多维)中的网格中查找相邻单元格

def find_adjacent_cells(grid):
    rows = len(grid)
    cols = len(grid[0])
    result = []

    for i in range(rows):
        for j in range(cols):
            cell_sum = 0

            # 上方单元格
            if i > 0:
                cell_sum += grid[i-1][j]
            # 下方单元格
            if i < rows - 1:
                cell_sum += grid[i+1][j]
            # 左方单元格
            if j > 0:
                cell_sum += grid[i][j-1]
            # 右方单元格
            if j < cols - 1:
                cell_sum += grid[i][j+1]

            result.append(cell_sum)

    return result
