Is there a reason you don't keep the original code and just wrap it in a the if/else that you creates here?

This seemed better in terms of clarity. I believe using list() and items() iterates twice as well which is worse for performance but that's not a big deal here.

That makes sense. I am still slightly confused why you are indexing the dict with the course_id. Is that how you get the image url? If you could add a comment in to code to clarify this it would help me understand more.

I thought the video looked like this from working it out backwards. And current_course is only populated with entries if course_id in c.
video = {
'courses': [
{
'course_id_123': 'img.url',
...
},
],
}

Thanks for the example! It definitely clears up my confusion

Description
When there is corruption in course video data, we can run into the following error:
This causes the api to not return course video data even if one url is missing (and subsequently causes the course video page to not load at all).
This PR ensures that the IndexError is not triggered so the api call can at least return as much information as it can.

Testing instructions
Test on stage by accessing https://course-authoring.stage.edx.org/course/course-v1:edx+gc_6+2024_T1/videos/.
It should not show an error.
