What is the difference between lists and arrays in Python?

What is the difference between lists and arrays in Python?

In Python, lists are dynamic and can hold mixed data types, while arrays (from the array module) are more efficient for numerical data.

Can you give me an example of when to use a list instead of an array?

Sure! Use a list when you need to store different data types, like strings and integers together. Arrays are better for numerical computations.

Are there any performance differences between them?

Yes, arrays are generally faster for numerical operations due to their fixed size and type, while lists are more flexible but slower.

How do I create an array in Python?

You can create an array using the array module. For example: from array import array; my_array = array('i', [1, 2, 3]).

What about NumPy arrays? How do they compare?

NumPy arrays are more powerful than standard arrays, offering more functionality and better performance for large datasets.
