NumPy's `endswith(~)` method checks whether each string in the input array ends with the specified substring.

# Parameters

1. `a` | `array-like`

The input array of strings.

2. `suffix`link | `array-like`

The ending substring you want to check for.

3. `start`link | `int` | `optional`

The starting index to begin our check (inclusive).

4. `end`link | `int` | `optional`

The index to end to check until (inclusive).

# Return value

If `a` is a scalar, then a single boolean is returned. Otherwise, a NumPy array of booleans is returned.

# Examples

## Specifying suffix

``` np.char.endswith(["abcde"], ["de"]) array([ True]) ```

## Specifying start

``` np.char.endswith(["abcde"], ["de"], start=1) array([True]) ```

Here, we are starting at index 1, which means that we're checking against the string `"bcde"`.

## Specifying end

``` np.char.endswith(["abcde"], ["cde"], end=2) array([False]) ```

Here, we are ending at index 2, which means that we're checking against the string `"ab"`, which obviously does not end with `"cde"`.
