so I have to create a List of a big range and am trying to accomplish this with list(range(number1, number2))and the numbers number1 and number2 can have a big difference, for example 235 and 4323246376. Now, this takes a long time to process. Can this process be sped up?

If you're only looking to use the list as a filter to count items in another list, you should not be using a range at all.

For example:

count = numpy.sum(theList >= 235) - numpy.sum(theList >= 4323246376)

What use case are you going to achieve with this?

In case you are going to use this list once, don't typecast the range object into a list. When you typecast the range object into a list, It stores all the numbers in a list which costs you memory. You can just iterate over the range object.
