请将以下代码的语法进行优化，使其更清晰易读：
```python
def func(x, y, z):
   x = x + 1
   y = y + 1
   z = z + 1
   return x, y, z
```
下面是一段优化后的代码例子，提供更多的上下文信息：
```python
def increment_values(x, y, z):
    # Increment each value by 1
    x += 1
    y += 1
    z += 1
    return x, y, z
```

```python
def increment_values(x, y, z):
    # Increment each value by 1
    x += 1
    y += 1
    z += 1
    return x, y, z
```
