What is the syntax for building a list in Python?

In Python, a list is created by enclosing comma‑separated values in square brackets. For example: my_list = [1, 2, 3] creates a list of three integers. You can also build a list from an iterable using a list comprehension: squared = [x*x for x in range(10)]. Lists are mutable, so you can append, remove, or modify elements after creation: my_list.append(4) adds an element to the end. The syntax [ ] is the most common way to build a list literal, and it can contain any type of object, including nested lists like nested = [[1, 2], [3, 4]]. Remember that the comma is required between elements; omitting it will cause a syntax error. Lists are the default sequence type in Python and are used for most dynamic collections.
