    Args:
        n: The non-negative integer for which to calculate the factorial.

    Returns:
        The factorial of n.
    """
    result = 1
    for i in range(1, n):
        result *= i
```
Use code with caution.
Copilot automatically populates a docstring template with placeholders for arguments and return values. You can further customize this docstring with additional details specific to your function.
