Lists in Python: The Mutable Data Structure
In the previous module, you learned about functions in Python and in this one, you are going to the next step which is Lists in Python. They are one of the most prominent features of Python and it is useful in ordering the elements.
Let's learn more about it in this article.
Lists in Python:
Lists in Python are versatile and mutable collections of items. They provide an ordered sequence of elements that can be of any data type, allowing you to store and manipulate different data types, variables, and strings. Lists are created using square brackets [] and can be populated with values during initialization or modified dynamically.
With indexing and slicing, you can access individual elements or extract portions of a list. Python lists offer various operations and methods for concatenating, repeating, and modifying elements. They are widely used for data storage, sequence handling, and as building blocks for more complex data structures. Being mutable, lists allow you to add, remove, and modify elements, making them a powerful tool in Python programming.
Syntax of Lists in Python:
The syntax for creating a list in Python is as follows:
>>> my_list = [element1, element2, element3, ...]
Here, 'my_list' is the name of the list variable, and 'element1, element2, element3,' and so on, are the elements you want to include in the list. Elements are separated by commas and enclosed within square brackets [].
You can create lists of integers, strings or even different data types, for example:
>>> numbers = [1, 2, 3, 4, 5]
This is a list of integers that contains elements in integer form.
>>> fruits = ["apple", "banana", "orange"]
This is a list containing strings.
>>> mixed_list = [1, "hello", 3.14, True]
This is a list containing different types of data types.
