​
Input

  • input: The original input text or data
  • output: The string to validate as a hex color code
  • 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 hex color code
  • false: The string is not a valid hex color code
This evaluator requires a function named validate.

​
Example

import re

def validate(input, output, expectedOutput):
    pattern = r'^#?[0-9A-Fa-f]{3}([0-9A-Fa-f]{3})?$'
    return re.match(pattern, str(output)) is not None
