How do i reference values from various ranges within a list?

Question

What I want to do is reference several different ranges from within a list, i.e. I want the 4-6th elements, the 12 - 18th elements, etc. This was my initial attempt:

test = theList[4:7, 12:18]

Which I would expect to give do the same thing as:

test = theList[4,5,6,12,13,14,15,16,17]

But I got a syntax error. What is the best/easiest way to do this?

Answer 1

You can add the two lists.

>>> theList = list(range(20))
>>> theList[4:7] + theList[12:18]
[4, 5, 6, 12, 13, 14, 15, 16, 17]
