Lists within a list

So far, we have discussed lists, tuples, dictionaries, sets as a sequence.

But we can chain these data types together to create say, a list within a list, list within a tuple and so on.

Codepython

list1 = list(range(4))
list1

Output

[0, 1, 2, 3]

Codepython

list2 = ["one", "two", "three", "four"]
list2

Output

['one', 'two', 'three', 'four']

We have the append method to append anything inside a list. Lets see what happens when we append a list to another list.
