❓ Norman Doors - How, “Not” to Design Arguments, Parameters, and Return Statements#

A Norman door is a term for a poorly designed door that confuses users about whether to push or pull, often due to unclear visual or tactile cues. Coined by Don Norman in The Design of Everyday Things, it highlights the failure of the design to communicate its function intuitively, often requiring labels like “PUSH” or “PULL” to compensate. Good design avoids such confusion by aligning the door’s appearance and affordances (e.g., handles or flat plates) with its intended operation, ensuring usability without explanation.

Question 1 (Points: 6.0): Create a Function to Evaluate Door Usability#

Write a Python function named evaluate_door that:

  • Accepts two arguments: handle_type (a string) and door_action (a string).

  • Returns "Confusing" if:

    • The handle type is “pull” but the action is “push”.

    • The handle type is “push” but the action is “pull”.

  • Returns "Clear" if the handle type matches the action.

...

print(evaluate_door("pull", "push")) # Should print Confusing
print(evaluate_door("push", "push")) # Should print Clear

grader.check("Door-Assessment")

Question 2 (Points: 5.0): Create a Function to Recommend Door Fixes#

Write a Python function named recommend_fix that:

  • Accepts two arguments: handle_type (a string) and door_action (a string).

  • Returns a string recommendation:

    • "Change the handle" if the handle type does not match the action.

    • "No changes needed" if the handle type matches the action.

...

# Example usage
print(recommend_fix("pull", "push")) # Should print Change the handle
print(recommend_fix("push", "push")) # Should print No changes needed

grader.check("Door-Recommendations")
