An example of an AI chatbot conversation about creating a 2D array in Python.
How do I create a 2D array in Python?
You can create a 2D array in Python using lists. For example, you can use a list of lists: array = [[1, 2], [3, 4]].
Can you show me how to access elements in that array?
Sure! You can access elements using their indices. For example, array[0][1] will give you 2.
What if I want to create a 2D array with all zeros?
You can use list comprehension: array = [[0 for _ in range(columns)] for _ in range(rows)].
Is there a library that can help with 2D arrays?
Yes, you can use NumPy, which provides a powerful array object. You can create a 2D array with numpy.array([[1, 2], [3, 4]]).
