Returns the weighted average of two or more numbers.

- Use
`sum()`

to sum the products of the numbers by their weight and to sum the weights. - Use
`zip()`

and a list comprehension to iterate over the pairs of values and weights.

```
def weighted_average(nums, weights):
return sum(x * y for x, y in zip(nums, weights)) / sum(weights)
```

`weighted_average([1, 2, 3], [0.6, 0.2, 0.3]) # 1.72727`
