Lists:

Lists are ordered collections of items that can be of any data type, including other lists.
Lists are defined using square brackets [] and items are separated by commas. For example, `[1, 2, 3]` is a list with three items.
Lists can be indexed (accessed) using integer keys, starting at 0. For example, `my_list[0]` would return the first item in the list.
Lists can be sliced to extract a subset of the items. For example, `my_list[1:3]` would return the second and third items in the list.

Tuples:

Tuples are similar to lists, but they are immutable, meaning they cannot be changed once they are created.
Tuples are defined using parentheses () and items are separated by commas. For example, `(1, 2, 3)` is a tuple with three items.
Tuples cannot be altered or resized, but they can be indexed and sliced like lists.

Dictionaries:

Dictionaries are unordered collections of key-value pairs, where each key is unique and maps to a specific value.
Dictionaries are defined using curly braces {} and keys are separated from values using a colon. For example, `{ 'name': 'Shako', 'age': 3 }` is a dictionary with two key-value pairs.
Dictionaries can be accessed using their keys, and values can be retrieved using the index notation. For example, `my_dict['name']` would return the value associated with the key 'name'.
