用python的for循环，打印九九乘法表

Python:

#! /usr/bin/env python

# -*- coding:utf-8 -*-

for row in range(1, 10):

    for col in range(1,row + 1):

       

        print("%d * %d = %d" % (col, row, row * col), end=" " )

      

print(" ")     

运行结果：

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
