And what has been the problem?

I'm not familiar with NumPy (which I assume is what you are using?)
However the second approach looks more likely to succeed than the first. 
Assuming enumerate works with NumPy arrays. Is there any
reason why you cannot use a normal list?

Then it would just be:

result = sum(1 for item in array if item >= 100)

HTH,
