​
Input

  • input: The original input text or data
  • output: The URL string to validate
  • expectedOutput: The expected output to compare against.
  • Any of the input variables (input, output, expectedOutput) can be marked as optional.
  • The returned value from the validate function can be a boolean, string, or a number.

​
Output

  • Result: Boolean (true or false) | string | number

​
Interpretation

Assuming this evaluator returns a boolean
  • true: The string is a valid URL
  • false: The string is not a valid URL
This evaluator requires a function named validate.

​
Example

from urllib.parse import urlparse

def validate(input, actual_output, expected_output):
    """
    Returns True if actual_output is a syntactically valid URL with an allowed scheme and non-empty netloc.
    expected_output is unused for this evaluator but kept for interface consistency.
    """
    try:
        url = str(actual_output).strip()
        parsed = urlparse(url)
        return parsed.scheme in ("http", "https", "ftp") and bool(parsed.netloc)
    except Exception:
        return False
