A list in Python is an ordered, mutable collection of elements, which can be of any data type. Lists are created using square brackets [] and elements are separated by commas. You can access, modify, add, or remove elements using various methods.
Key Operations:
Creating a list: my_list = [1, 2, 3]
Accessing elements: my_list[0] (returns 1)
Modifying elements: my_list[0] = 10
Adding elements: my_list.append(4)
Removing elements: my_list.pop()
Slicing: my_list[1:3] (returns a sublist)
Lists support iteration, and you can use list comprehension for concise creation. Methods like sort(), reverse(), and len() are commonly used.
