NumPy's `randint()` returns a NumPy array of random integers that are in the specified range.

# Parameters

1. `low`link | `int`

The lower bound (inclusive).

2. `high`link | `int` | `optional`

The upper bound (exclusive). If not specified, then the range would be from 0 (inclusive) to `low` (exclusive).

3. `size`link | `int` or `sequence` of `int` | `optional`

The desired number of random values to generate. By default, `size=1`.

4. `dtype`link | `string` or `type` | `optional`

The desired data type of the generated values. By default, `dtype=np.int`.

# Return value

A NumPy array of random integers in the specified range. If `size` is not specified, a scalar is returned.

# Examples

## Generate a random integer between 0 (inclusive) and 5 (exclusive)

``` np.random.randint(5) 2 ```

## Generate a random integer between 2 (inclusive) and 5 (exclusive)

``` np.random.randint(2, high=5) 4 ```

## Generate 10 random integers between 2 (inclusive) and 5 (exclusive)

``` np.random.randint(2, high=5, size=10) array([2, 3, 3, 2, 3, 2, 3, 3, 3, 4]) ```

## Generating a multi-dimensional array of random numbers

``` np.random.randint(2, high=10, size=(2,3)) array([[9, 4, 8], [4, 6, 5]]) ```

## Specifying a custom data-type

``` np.random.randint(2, high=5, dtype=np.int) 4 ```
