How to extract elements from a nested list in Python?

To extract elements from a nested list, you can use a double loop to iterate through the nested list. Here is an example code:

nested_list = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]

for sublist in nested_list:
    for element in sublist:
        print(element)

The code above will output each element in the nested list one by one. If you need to retrieve a specific element based on its index, you can do so by using index access, such as nested_list[1][2] to retrieve the third element in the second sublist.
