  ```python
  class Bicycle():
      def __init__(self, brand, colour):
          self.brand = brand
          self.colour = colour
  
  def get_bicycle_attributes(brand, colour):
      bike = Bicycle(brand, colour)
      return (bike.brand, bike.colour)
  
  assert get_bicycle_attributes('Trek', 'Red') == ('Trek', 'Red')
  assert get_bicycle_attributes('Giant', 'Blue') == ('Giant', 'Blue')
  assert get_bicycle_attributes('Specialized', 'Black') == ('Specialized', 'Black')
output: def get_bicycle_attributes(brand, colour):
      bike = Bicycle(brand, colour)
      return (bike.brand, bike.colour)
