Ever wondered how machine learning models process audio data? How do you handle different audio lengths, convert sound frequencies into learnable patterns, and make sure your model is robust? This tutorial will show you how to handle audio data using TorchAudio, a PyTorch-based toolkit. You’ll work with real speech data to learn essential techniques like converting waveforms to spectrograms, standardizing audio lengths, and adding controlled noise to build machine and deep learning models. Dive into the tutorial to explore these […]

Interactive Quiz ⋅ 12 QuestionsBy Bartosz Zaczyński Share In this quiz, you’ll test your understanding of Your Guide to the Python print() Function. The print() function outputs objects to the console or a specified file-like stream. You’ll practice: Printing multiple values with custom separators Changing the end-of-line character Redirecting output using the file parameter Forcing immediate output with the flush parameter Work through these questions to reinforce your knowledge of print()’s parameters and best practices for clear, formatted I/O. The […]

If you’re like most Python users, then you probably started your Python journey by learning about print(). It helped you write your very own “Hello, World!” one-liner and brought your code to life on the screen. Beyond that, you can use it to format messages and even find some bugs. But if you think that’s all there is to know about Python’s print() function, then you’re missing out on a lot! Keep reading to take full advantage of this seemingly […]

The DuckDB database provides a seamless way to handle large datasets in Python with Online Analytical Processing (OLAP) optimization. You can create databases, verify data imports, and perform efficient data queries using both SQL and DuckDB’s Python API. By the end of this video course, you’ll understand that: You can create a DuckDB database by reading data from files like Parquet, CSV, or JSON and saving it to a table. You query a DuckDB database using standard SQL syntax within […]

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: Looping With Python enumerate() Python’s enumerate() function helps you with loops that require a counter by adding an index to each item in an iterable. This is particularly useful when you need both the index and value while iterating, such as listing items with their positions. You can also customize the starting index with […]
