Accessibility of chatbots
Definition and example
Accessibility of chatbots is the focus of this lesson. Keyboard reachable, labelled buttons, no auto-playing sound, clear close. The task asks you to apply that idea in a small example: What must a chatbot always provide. Before you run the code, predict what should happen. Then Inspect the result produced by the exercise and compare it with your prediction. If the result differs, change one relevant line and run it again. Testing one change at a time makes the cause of a result easier to understand.
