The NumPy library is a Python library used for scientific computing. It provides you with a multidimensional array object for storing and analyzing data in a wide variety of ways. In this tutorial, you’ll see examples of some features NumPy provides that aren’t always highlighted in other tutorials. You’ll also get the chance to practice your new skills with various exercises. If you’re new to NumPy, it’s a good idea to familiarize yourself with the basics of data science in […]

TOML—Tom’s Obvious Minimal Language—is a reasonably new configuration file format that the Python community has embraced over the last couple of years. TOML plays an essential part in the Python ecosystem. Many of your favorite tools rely on TOML for configuration, and you’ll use pyproject.toml when you build and distribute your own packages. In this video course, you’ll learn more about TOML and how you can use it. In particular, you’ll: Learn and understand the syntax of TOML Use tomli […]

There are multiple ways of interacting with Python, and each can be useful for different scenarios. You can quickly explore functionality in Python’s interactive mode using the built-in Read-Eval-Print Loop (REPL), or you can write larger applications to a script file using an editor or Integrated Development Environment (IDE). In this tutorial, you’ll learn how to: Use Python interactively by typing code directly into the interpreter Execute code contained in a script file from the command line Work within a […]

Watch Now This tutorial has a related video course created by the Real Python team. Watch it together with the written tutorial to deepen your understanding: Parallel Iteration With Python’s zip() Function Python’s zip() function combines elements from multiple iterables. Calling zip() generates an iterator that yields tuples, each containing elements from the input iterables. This function is essential for tasks like parallel iteration and dictionary creation, offering an efficient way to handle multiple sequences in Python programming. By the […]
