How to implement a dynamic array or list of elements in Python, considering the features of built-in data structures?

In Python, a dynamic array is implemented using the built-in data type list. It allows storing an ordered collection of elements, automatically expanding when new elements are added.

Example of using a list as a dynamic array:

arr = []  # empty list
arr.append(10)  # add element
arr.append(20)
print(arr)  # [10, 20]

# you can also modify elements by index
arr[0] = 5
print(arr)  # [5, 20]

Lists in Python are convenient because they do not require pre-defining the size and support many operations for working with elements.
