Question

I was looking at the following code in python:

for ob in [ob for ob in context.scene.objects if ob.is_visible()]:
    pass

Obviously, it’s a for each loop, saying for each object in foo array. However, I’m having a bit of trouble reading the array. If it just had:

[for ob in context.scene.objects if ob.is_visible()]

that would make some sense, granted the use of different objects with the same name ob seems odd to me, but it looks readable enough, saying that the array consists of every element in that loop. However, the use of ‘ob’, before the for loop makes little sense, is there some syntax that isn’t in what I’ve seen in the documentation?

Thank you

Answer 1

That is the syntax for list comprehension.
