Python List: A Flexible Data Type

What Python data type is roughly like a Java array?

1. Tuple

2. List

3. Dictionary

4. Set

Answer:

2. List

In Python, a list is a collection of elements that can be of any data type. Lists can be modified (elements added, removed, or replaced) and can contain duplicate elements. A list can be created by enclosing a sequence of elements in square brackets, separated by commas. For example:

my_list = [1, 2, "three", True, 4.5]

To access elements in a list, use square brackets and the index of the element (starting at 0 for the first element). For example, to access the first element of the above list, use:

my_list[0]

Lists in Python are similar to arrays in Java, but they are more flexible and dynamic. They can grow or shrink as needed, and they can contain elements of different data types.

Thus, a Python data type that is roughly like a Java array is known as a list.
