### Understanding the `getMaxDigit` Function in Python

The following code snippet demonstrates the usage of a Python function named `getMaxDigit`. This function seems to identify the maximum digit present within a given string. Let's walk through the examples:

```python
>>> s = getMaxDigit('')
>>> s
''
```
**Explanation:**
An empty string is passed to `getMaxDigit`. The function returns an empty string since there are no digits in the input.

```python
>>> s = getMaxDigit('Testing, testing, 1, 2, 3!')
>>> s
'3'
>>>
>>> type(s)
<class 'str'>
```
**Explanation:**
The string "Testing, testing, 1, 2, 3!" is passed to `getMaxDigit`. The function scans the string and identifies '3' as the highest digit. The result is a string containing '3'. Also, the type of `s` is confirmed to be `<class 'str'>`.

```python
>>> s = getMaxDigit("10, 9, 8, 7, 6, 5, 4, 3, 2, 1, blast off!!")
>>> s
'9'
```
**Explanation:**
The string "10, 9, 8, 7, 6, 5, 4, 3, 2, 1, blast off!!" is input to `getMaxDigit`. Among the digits present, '9' is the highest, so the function returns '9'.

```python
>>> s = getMaxDigit("8, 7, 6, wait, 8 again!")
>>> s
'8'
```
**Explanation:**
The function processes the string "8, 7, 6, wait, 8 again!" and identifies '8' as the maximum digit, returning '8'.

```python
>>> s = getMaxDigit('This has no digits')
>>> s
''
```
**Explanation:**
For the string "This has no digits", the function returns an empty string as there are no numeric digits present in the input.

---

### Summary

- The `getMaxDigit` function is designed to identify and return the highest numeric character in a given string.
- If no digits are found, the function returns an empty string.
- The examples shown demonstrate various inputs, including strings with multiple digits,
