Return list of items in list greater than some value

You can use a list comprehension to filter it:

j2 = [i for i in j if i >= 5]

If you actually want it sorted like your example was, you can use sorted:

j2 = sorted(i for i in j if i >= 5)

Or call sort on the final list:

j2 = [i for i in j if i >= 5]
j2.sort()
