For: l1 = [1, 2, 3] and l2 = [7, 3, 4] and l3 = [] you can:

append elements

l3.append(l1) and l3.append(l2)

create directly

l3 = [l1, l2]

add

l3 = [l1] + [l2]

In this case you can use

l3=[l1,l2]

If you want to insert l2 into l1 at some particular index you can make use of .insert function of lists

list.insert(index,object)
l1.insert(2,l2)

Hope it helps.

You can simply do something like this:

>>> l1=[1,2,3]
>>> l2=[7,3,4]
>>> [l1, l2]
[[1, 2, 3], [7, 3, 4]]

Based on your update not requiring pandas, you can simply do this:

l1=[1,2,3]
l2=[7,3,4]

l3 = [l1] + [l2]

Output:

[[1, 2, 3], [7, 3, 4]]
