Question

Accessing lists within lists and indexing the desired list to extract a value?

Answer 1

To access lists within lists and index the desired list to extract a value, use nested indexing in programming languages like Python.

Step-by-step explanation:

To access lists within lists and index the desired list to extract a value, you can use nested indexing in programming languages like Python. For example, if you have a list called outer_list and inside it, there is another list called inner_list, you can access the value of inner_list by using the indexes of both lists: value = outer_list[index1][index2].

Here's an example:

outer_list = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
value = outer_list[1][2] # Accesses the value 6
print(value) # Output: 6
