I tried to map the function `math.pow` with the power of 2 to a list,
but the problem is that I should pass an iterable not just a single value.
So, I fixed it this way, by making a list of 2s with the same length as my list:

```
import math
lis = [1,2,3,4]
squred_lis = list(map(math.pow, lis, [2,2,2,2]))
print (squred_lis)

```

So, is there a way I can just pass a single value and have it passed every iteration as the second argument?
