I have two lists in Python:

```
a = [1, 5, 5]
b = [2, 10, 8]
```

If `1 < 2`

and `5 < 10`

and `5 < 8`

, that is, if each element of the list `a`

is less than its corresponding element list `b`

, then the variable `c`

will be% `1`

; if it will not be worth `0`

.

I tried to do it using `numpy.where`

but then I can not find a function that says if the resulting vector is empty or not (an equivalent to `isempty`

of matlab)

This is what I have tried for the moment:

```
a = [10, 10, 10]
b = [1, 1, 1]
a = np.asarray(a)
b = np.asarray(b)
if np.where(abs(a) / 5 < abs(b)): residual_check = 1
else: residual_check = 0
print(residual_check)
```

How could I do it?
