如何在网格中查找行中元素的和

def find_row_sum(grid):
    sum = 0
    for row in grid:
        rowSum = 0
        for num in row:
            rowSum += num
        sum += rowSum
    return sum

# 示例网格
grid = [
    [1, 2, 3],
    [4, 5, 6],
    [7, 8, 9]
]

# 调用函数查找行中元素的和
result = find_row_sum(grid)
print("网格中行中元素的和为:", result)

网格中行中元素的和为: 45
