Here's how you can write the code for this requirement:

```python
def check_num(num):
"""
Checks if a number is positive, negative, or zero.

Args:
num (int): The number to be checked.

Returns:
None
"""
# Check if the number is greater than 0 and log an appropriate message
if num > 0:
print(f"The number {num} is positive.")

# If the number is not greater than 0, check if it's less than 0
elif num < 0:
print(f"The number {num} is negative.")

# Check for any other cases where the number might be 0
else:
print(f"The number {num} is zero.")

# Example usage
check_num(16)
```

This Python function takes an integer `num` as input and logs a message based on whether the number is positive, negative, or zero.
