Python Question

I have a numpy array of numbers, for example,

`a = [1, 3, 5, 6, 9, 10, 14, 15, 56]`

I would like to find all elements within a specific range. For instance, if the range is (6, 10), the answer should be (3, 4, 5). Is there a built-in function to do this?

You can use `np.where`

to get indices and `np.logical_and`

to set two conditions:

```
In [27]: a = np.array([1, 3, 5, 6, 9, 10, 14, 15, 56])
In [28]: np.where(np.logical_and(a>=6, a<=10))
Out[28]: (array([3, 4, 5]),)
```
