Python基础学习：打印九九乘法表

说明：
加一个条件判断是为了防止错位，不加判断的话在结果为两位数的话会错位

# import sys
i = 0
while i < 9:
    i += 1
    for j in range(1, i+1):
        s = '%s * %s' % (i, j)
        # sys.stdout.write(s+' = %s' % (str(i*j)))
        # sys.stdout.write('   ')
         if i*j >= 10:
            print(s + ' = %s' % (str(i * j)), end='    ') # 四个空格
        else:
            print(s+' = %s' % (str(i*j)), end='     ') # 五个空格
    print('')

打印出来结果：

1 * 1 = 1     
2 * 1 = 2     2 * 2 = 4
