Why do you want to do it in pandas, you can do it in just normal python.Nafiul Islam– Nafiul Islam2016-04-29 09:52:20 +00:00Commented Apr 29, 2016 at 9:52

You can simply do something like this:
>>> l1=[1,2,3]
>>> l2=[7,3,4]
>>> [l1, l2]
[[1, 2, 3], [7, 3, 4]]

You can just do this
l3 = [l1,l2]

and i have another one doubt
Sai Rajesh
is it possible to converts particular columns to convert lists..?
Sai Rajesh
in my dataframe there are 5 columns...i wants convert particular 3 columns into lists
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]

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]]

That is exactly the output that I'm getting. Are you sure you included the square brackets?
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.
