用for循环实现九九乘法

当然可以，用for循环实现九九乘法表是一种常见的编程练习。下面是一个简单的Python示例：

# 初始化两个嵌套的for循环，i表示行数，j表示列数
for i in range(1, 10):
    # 对于每一行
    for j in range(1, i+1):  # 列数只到当前行数
        # 计算乘积并打印结果
        product = i * j
        print(f"{j} * {i} = {product}", end="\t")  # "\t"用于添加制表符，使得输出更美观
    # 每一行结束后换行
    print()

这个程序会逐行打印出1到9的乘法表。运行它，你将看到如下的输出：

1 * 1 = 1	
1 * 2 = 2	2 * 2 = 4	
1 * 3 = 3	2 * 3 = 6	3 * 3 = 9	
1 * 4 = 4	2 * 4 = 8	3 * 4 = 12	4 * 4 = 16	
1 * 5 = 5	2 * 5 = 10	3 * 5 = 15	4 * 5 = 20	5 * 5 = 25	
1 * 6 = 6	2 * 6 = 12	3 * 6 = 18	4 * 6 = 24	5 * 6 = 30	6 * 6 = 36	
1 * 7 = 7	2 * 7 = 14	3 * 7 = 21	4 * 7 = 28	5 * 7 = 35	6 * 7 = 42	7 * 7 = 49	
1 * 8 = 8	2 * 8 = 16	3 * 8 = 24	4 * 8 = 32	5 * 8 = 40	6 * 8 = 48	7 * 8 = 56	8 * 8 = 64	
1 * 9 = 9	2 * 9 = 18	3 * 9 = 27	4 * 9 = 36	5 * 9 = 45	6 * 9 = 54	7 * 9 = 63	8 * 9 = 72	9 * 9 = 81
