Narwhals is intended for Python library developers who need to analyze DataFrames in a range of standard formats, including Polars, pandas, DuckDB, and others. It does this by providing a compatibility layer of code that handles any differences between the various formats. In this tutorial, you’ll learn how to use the same Narwhals code to analyze data produced by the latest versions of two very common data libraries. You’ll also discover how Narwhals utilizes the efficiencies of your source data’s […]

Interactive Quiz ⋅ 5 QuestionsBy Leodanis Pozo Ramos Share In this quiz, you’ll test your understanding of the Python Inner Functions: What Are They Good For? tutorial. By working through this quiz, you’ll revisit how inner functions work with enclosing scopes, when to use nonlocal to update captured state, how closures retain data across calls, and how decorators wrap a callable to extend behavior. You’ll apply these ideas to organize helpers, reuse state, and write clear, maintainable functions in real […]

A lot happened last month in the world of Python! The core developers pushed ahead on Python 3.15, accepting PEP 810 to bring explicit lazy imports to the language. PyPI tightened account security, Django 6.0 landed with a slew of new features while celebrating twenty years of releases, and the Python Software Foundation (PSF) laid out its financial outlook and kicked off a year-end fundraiser. Let’s dive into the biggest Python news from the past month! Python Releases and PEP […]

The pandas DataFrame is a structure that contains two-dimensional data and its corresponding labels. DataFrames are widely used in data science, machine learning, scientific computing, and many other data-intensive fields. DataFrames are similar to SQL tables or the spreadsheets that you work with in Excel or Calc. In many cases, DataFrames are faster, easier to use, and more powerful than tables or spreadsheets because they’re an integral part of the Python and NumPy ecosystems. In this video course, you’ll learn: […]

Interactive Quiz ⋅ 7 QuestionsBy Martin Breuss Share Dive into quantum computing fundamentals with this quiz.

Every classical computer reduces the world to 0s and 1s. That binary framework has carried us from calculators to supercomputers, but some problems demand checking through 2n possibilities, a task that outpaces even the best machines. Now, what if information could exist in many states at once? That what if turned into a new model called quantum computation. Keep reading to break with binaries and get an overview of quantum computing basics. By the end of this tutorial, you’ll understand […]
