Python九九乘法表输出。工整打印输出 常用的九九乘法表

在Python中，我们可以使用嵌套循环和字符串格式化来创建一个整洁的九九乘法表。以下是一个简单的例子：

for i in range(1, 10):
    # 外层循环控制行数
    for j in range(1, i + 1):
        # 内层循环控制列数，使用'\t'实现对齐
        print(f'{j} * {i} = {i*j}\t', end='')
    # 每行结束后换行
    print()

运行这段代码后，你会在控制台看到九九乘法表，每一行的乘法表达式都对齐排列，例如：

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
