Learn how and when to use the len() Python function. You'll also learn how to customize your class definitions so that objects of a user-defined class can be used as arguments in len().

Tutorial

In this tutorial, you'll dive deep into Python's lists. You'll learn how to create them, update their content, populate and grow them, and more. Along the way, you'll code practical examples that will help you strengthen your skills with this fundamental data type in Python.

Tutorial

What's the difference between a shallow and a deep copy of a Python object? Learn how to clone arbitrary objects in Python, including your own custom classes.

Course

Python list comprehensions make it easy to create lists while performing sophisticated filtering, mapping, and conditional logic on their members. In this course, you'll learn when to use a list comprehension in Python and how to create them effectively.

Course

In Python, a tuple is a built-in data type that allows you to create immutable sequences of values. The values or items in a tuple can be of any type. This makes tuples pretty useful in those situations where you need to store heterogeneous data, like that in a database record, for example.

Course

In this step-by-step course, you’ll learn how to sort in Python. You'll know how to sort various types of data in different data structures, customize the order, and work with two different ways of sorting in Python.

Course

Learn how to work with Python's set data type. You'll see how to define set objects in Python and discover the operations that they support. By the end of this course, you'll have a good feel for when a set is an appropriate choice in your own programs.

Tutorial

Learn about Python's bytes objects, which help you process low-level binary data. You'll explore how to create and manipulate byte sequences in Python and how to convert between bytes and strings. Additionally, you'll practice this knowledge by coding a few fun examples.

Interactive Quiz

Tutorial

Learn about Python's bytearray, a mutable sequence of bytes for efficient binary data manipulation. You'll explore how it differs from bytes, how to create and modify bytearray objects, and when to use them in tasks like processing binary files and network protocols.

Tutorial

Learn how Python's del statement works and how to use it in your code. This statement will allow you to remove references from different scopes, items from lists, keys from dictionaries, and members from classes. This will lead to potentially memory-efficient code.

Tutorial

Learn how to use Python's assignment operators to write assignment statements that allow you to create, initialize, and update variables in your code.

Course

In this step-by-step course, you'll master the Python range() function, learn how its implementation differs in Python 3 vs 2, and see how you can use it to write faster and more Pythonic code.

Tutorial

In Python, range() is most commonly used in for loops. However, ranges have some other use cases too, as they share many properties with lists. In this tutorial, you'll explore why it's so fast to perform a membership test on a Python range.

Tutorial

Learn about the unique treatment of complex numbers in Python. Complex numbers are a convenient tool for solving scientific and engineering problems. You'll experience the elegance of using complex numbers in Python with several hands-on examples.
