如何用python输出99乘法表

方法：1、利用“for i in range(1,9)” 控制打印的行数；2、利用“for j in range(1, i+1)”控制打印的列数；3、利print(f"{j} * {i} = {i * j}")语句打印，即可显示九九乘法表。

第一个for循环1， 9控制打印的行数

内侧for循环控制每一行的列数

for i in range(1, 10):
    for j in range(1, i+1):
        print(f"{j} * {i} = {i * j}", end="\t")
    print()

结果是：

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
