Copying a sublist into a main list as objects instead of lists

Question

child = []
parent = [1, 3, 5, 7, 9]
index = 2
child.append(parent[:index])

When I have this code run, instead of returning me a child list of

child = [1, 3]

I get a child list of:

child = [[1, 3]]

Is there a single line method of copying a few objects of a list into another list without making it into a nested list?

Briefly: use `extend` rather than `append`. – TigerhawkT3 Jun 21 '16 at 00:32 — TigerhawkT3, Jun 21 '16 at 00:32

Try this:

child.extend(parent[:index])
