Parsing data with RegEx - study missmatch?

Question

Hi there,

in the interactive lessons for Alteryx Advance section /Creating Regular Expressions/ you can find a help how to manage digits in the whole sentence. In our case - see pict. 1 - it says "\d{4}".

After running the lessons/video it will allow only to fill in the possibility \d{4} otherwise it will not let you continue in the lesson.

Which one is the correct answer please and can someone from Alteryx adjust/repair the video?

thank you

Quotation marks means literally quotation here.

So the correct answer is the string within the " " marks.

Hi @SNSokol,

Like @Qiu mentioned those are only quotation marks. The question should be asked if the lessons are consistent. They have provided quotation marks for the rest of the answers or this was an exception.

If this was an exception I would totally agree with you that it is a problem and it should be changed.
