Creating a list from a sequence without while-loop

[schniefen]

Suppose I have a sequence [x][/n]. I want to create a list of [x][/n] for all n>0 as long as [x][/n] is greater than a given constant. I'm confused on how to go about this. I have defined the sequence as a function, but simply don't understand how one would solve this with a for-loop for example. I keep trying to find a way to create a range(0, infinity), but this gets very convoluted. Any help would be appreciated.

If you already have a sequence, and you want a subset of that sequence, you wouldn't use a while loop or for i in range(Infinity): anyway. You'd just iterate over the sequence.
