[已解决]请问花括号该怎么输出啊

xxlxxl

1. import sys
   
2. a = int(sys.argv[1])
   
3. b = int(sys.argv[2])
   
4. c = int(sys.argv[3])
   
5. d = int(sys.argv[4])
   
6. e = int(sys.argv[5])
   
7. f = int(sys.argv[6])
   
8. V = a,b,c
   
9. U = d,e,f
   
10. print('V = ',{V})
    
11. print('U = ',{U})
    
12. VU = a * d + b * e + c * f
    
13. print('V • U =',VU )

我这个输出后花括号里面有小括号，如果直接在定义V 和U 的时候就加花括号会对里面的数排序。

1. import sys
   
2. 
   
3. a = [int(x) for x in sys.argv[1:]]
   
4. V = a[0:3]
   
5. U = a[3:]
   
6. print(r'{%d, %d, %d}' % tuple(V))
   
7. print(r'{%d, %d, %d}' % tuple(U))
   
8. VU = a[0] * a[3] + a[1] * a[4] + a[2] * a[5]
   
9. print('V • U =', VU)

贴原题目吧，英文我们能看懂。

最后一行修改为 print('V · U ={%d}'%VU )

1. import sys
   
2. a = int(sys.argv[1])
   
3. b = int(sys.argv[2])
   
4. c = int(sys.argv[3])
   
5. d = int(sys.argv[4])
   
6. e = int(sys.argv[5])
   
7. f = int(sys.argv[6])
   
8. V = a,b,c
   
9. U = d,e,f
   
10. print(f'V = {V}')
    
11. print(f'U = {U}')
    
12. VU = a * d + b * e + c * f
    
13. print(f'V. U ={VU} ')

D:\python\test>python test.py 1 2 3 4 5 6
V = (1, 2, 3)
U = (4, 5, 6)
V. U =32

你是不是要这样啊？没看懂你的意思
