Looking for XBlock to provide "calculated question"

Educators Authoring
1

Hi all
We are running edX to provide LMS in our university. In some courses, we want to have multichoice question based on formular and parameters (as “calculated question” in Moodle: Calculated question type - MoodleDocs). Is there any Xblock to provide such similar function in edX? Very appreciate if anyone can provide comments or suggetion.

Thank you.

I think the typical solution to this is to use Python embedded in the course. There is some documentation here: 10.45. Write-Your-Own-Grader Problem — Building and Running an edX Course documentation

@Hoang_PHAM_HUY This snippet will do what that Moodle example does:

<problem>
<script type="loncapa/python">
w = random.randint(0, 10)
h = random.randint(0, 10)
area = w * h
</script>
  
    <label>Calculate the area of a rectangle, given the height and width below:</label>
    <p>Height = $h</p>
    <p>Width = $w</p>
    <numericalresponse answer="$area">
     <textline size="10"/>
    </numericalresponse>
      <solution>
          <div class="detailed-solution">
              <p>Explanation</p>
            <p>Multiply the width by the height to get the area.</p>
          </div>
      </solution>
</problem>
