How can I use Python data structures for the knapsack problem?

You can use lists or dictionaries in Python to represent items and their weights and values for the knapsack problem.

Can you show me a simple example using a list?

Sure! You can represent items as a list of tuples, where each tuple contains (weight, value). For example: items = [(2, 3), (3, 4), (4, 5)].

How do I implement the knapsack algorithm with this list?

You can use dynamic programming to solve it. Create a 2D array to store maximum values for each weight limit.

What if I want to use a dictionary instead?

You can use a dictionary to map weights to values, like this: knapsack = {2: 3, 3: 4, 4: 5}. Then adjust your algorithm accordingly.
