Python九九乘法表

代码:

# -*- coding: utf-8 -*-def multi_table():    result = ''    for i in range(1, 10):        for j in range(1, i + 1):            separator = '\n' if j == i else '\t'            result += '%d * %d = %-2d' % (j, i, i * j)            result += separator    return resultr = multi_table()print(r)

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 = 161 * 5 = 5  2 * 5 = 10 3 * 5 = 15 4 * 5 = 20 5 * 5 = 251 * 6 = 6  2 * 6 = 12 3 * 6 = 18 4 * 6 = 24 5 * 6 = 30 6 * 6 = 361 * 7 = 7  2 * 7 = 14 3 * 7 = 21 4 * 7 = 28 5 * 7 = 35 6 * 7 = 42 7 * 7 = 491 * 8 = 8  2 * 8 = 16 3 * 8 = 24 4 * 8 = 32 5 * 8 = 40 6 * 8 = 48 7 * 8 = 56 8 * 8 = 641 * 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
