How much credit should I ask? Or should I even?

I applied 2 months ago under early action.
I did a course of Python from coursera, the course on itself was non-credit course.
At present, they emailed me to answer a question, “How many postsecondary credits do you plan to transfer from work done with Coursera?”
What should I reply?

Honestly, I have no clue. I think it would be a good idea to try to explain what you learned in the course and ask how much credit that experience is typically worth.
