Lists Tuples and Dictionaries | python for beginners | python full course

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'.
