Hi Yi Jiang,

Try taking a look at the prompt at around 1:28 in the video.

You should see the prompt "Please type an adjective [3 questions left]"

The brackets are simply part of the prompt string. It was how Dave wanted the output to look but you can put whatever you want there.

Same here so it would not matter if I used () or [] in that string? Does that go for anytime we use () can we always substitute [] ?

Hi Mike,

If it's part of an output string then it wouldn't matter. It was only a personal preference on the part of the teacher to use the brackets.
