实验目的:
1.列表推导式使用方法
示例代码:

1. vec1 = [2, 4, 6]
   
2. vec2 = [4, 3, -9]
   
3. aa = [3*x for x in vec1]
   
4. bb = [[x, x**2] for x in vec1]
   
5. cc = [5*x for x in vec1 if x>3]
   
6. dd = [x*y for x in vec1 for y in vec2]
   
7. ee = [vec1[i]* vec2[i] for i in range(len(vec1))]
   
8. print(aa)
   
9. print(bb)
   
10. print(cc)
    
11. print(dd)
    
12. print(ee)
