Given a set of characters, write a function which checks whether the given set contains the character 'A'.
Here is a simple function in Python that takes a list of characters as an input and returns 'True' if the character 'A' is present in the list, and 'False' otherwise:

```python
def check_for_A(char_set):
    if 'A' in char_set:
        return True
    else:
        return False
```

Using this function, we can check whether the given set of characters contains the character 'A':

```python
char_set = ['W', 'X', 'Y', 'Z']
result = check_for_A(char_set)
print(result) #False
```
Character Set: [W, X, Y, Z]
Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.

### Instruction:
Given a set of characters, write a function which checks whether the given set contains the character 'A'.

### Input:
Character Set: [W, X, Y, Z]

### Response:
Here is a simple function in Python that takes a list of characters as an input and returns 'True' if the character 'A' is present in the list, and 'False' otherwise:

```python
def check_for_A(char_set):
    if 'A' in char_set:
        return True
    else:
        return False
```

Using this function, we can check whether the given set of characters contains the character 'A':

```python
char_set = ['W', 'X', 'Y', 'Z']
result = check_for_A(char_set)
print(result) #False
```
