实用：Python3实现打印加法口诀表

print('加法口诀表')
for i  in  range(1,10):
    for j in range(1,i+1):
        print('{:<2d}+{:>2d} = {:<2d} '.format(i , j , i + j) ,end = '  ')
    print('  ')

运行结果：

加法口诀表
1 + 1 = 2      
2 + 1 = 3    2 + 2 = 4      
3 + 1 = 4    3 + 2 = 5    3 + 3 = 6      
4 + 1 = 5    4 + 2 = 6    4 + 3 = 7    4 + 4 = 8      
5 + 1 = 6    5 + 2 = 7    5 + 3 = 8    5 + 4 = 9    5 + 5 = 10     
6 + 1 = 7    6 + 2 = 8    6 + 3 = 9    6 + 4 = 10   6 + 5 = 11   6 + 6 = 12     
7 + 1 = 8    7 + 2 = 9    7 + 3 = 10   7 + 4 = 11   7 + 5 = 12   7 + 6 = 13   7 + 7 = 14     
8 + 1 = 9    8 + 2 = 10   8 + 3 = 11   8 + 4 = 12   8 + 5 = 13   8 + 6 = 14   8 + 7 = 15   8 + 8 = 16     
9 + 1 = 10   9 + 2 = 11   9 + 3 = 12   9 + 4 = 13   9 + 5 = 14   9 + 6 = 15   9 + 7 = 16   9 + 8 = 17   9 + 9 = 18
