QUESTION 10 OF 21

Describe the differences between arrays and lists as Python uses them.

When asked to compare two items during an interview, you should begin by first defining each item. This will confirm that you are answering the question the interviewer asked you. You then briefly describe the differences, as requested. If applicable, you can provide examples of each of the items to illustrate their differences. As with any technical question, keep your answers brief and to the point, and anticipate follow-up questions.

"Arrays and lists, as used in Python, have many similarities since they are both methods for storing data. The key difference is that arrays can only hold a single type of data elements, while lists can contain any data type. An example is that array can contain only numbers or text, while a list can contain both numbers and text."
