How do I initialize an array in Python?

In Python, you can initialize an array using the array module or simply using a list. For example, you can create a list like this: my_list = [1, 2, 3].

What's the difference between a list and an array in Python?

A list in Python can hold items of different data types, while an array (from the array module) is more efficient for numerical data and requires all elements to be of the same type.

Can you show me how to use the array module?

Sure! First, you need to import the array module. Then, you can create an array like this: from array import array; my_array = array('i', [1, 2, 3]) where 'i' indicates the type of elements (integers in this case).
