What is the structure of the list data type in Python and how does it work?

In Python, a list is a mutable ordered collection of elements that can store objects of any type. It is implemented as a dynamic array, which provides fast access by index (O(1) operation) and relatively efficient appending of elements at the end.

Main features of list:

• Supports indexing and slicing.
• Allows storing duplicates and elements of different types.
• Mutable: elements can be added, removed, and modified.

Example usage:

my_list = [1, 'hello', 3.14]
my_list.append(42)  # adding an element
print(my_list[1])   # outputs 'hello'
my_list[0] = 100    # changing the first element
