I am new to python and I was just trying some list manipulations. I have three lists

```
A = [10,20,30,40,50,60]
B = [22,44,66,88,12,10]
C = [2,4,6,8,10,20]

```

I want to iterate over these three lists and for each value of C I want to add half of that value to the corresponding values of A and B. 
For example for the 1st iteration - 
half = 2/2= 1
So A = 10 + 1 and B = 22+1
So the final lists should look something like this

```
A = [11,22,33,44,55,70]
B = [23,46,69,92,17,20]
C = [2,4,6,8,10,20]

```
