How can I access elements in a nested list in Python?

How can I access elements in a nested list in Python?

You can access elements in a nested list by using multiple indices. For example, if you have a list like my_list = [[1, 2], [3, 4]], you can access the first element of the second list with my_list[1][0], which returns 3.

What if I want to access all elements in the nested lists?

You can use a loop to iterate through the nested lists. For example:

for sublist in my_list:
    for item in sublist:
        print(item)
``` This will print all elements.

Is there a way to flatten a nested list?

Yes, you can flatten a nested list using list comprehension. For example:

flat_list = [item for sublist in my_list for item in sublist]
``` This will give you a single list with all elements.
