Python’s pathlib Module: Taming the File System

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: Using Python’s pathlib Module Working with files and interacting with the file system are common tasks for Python developers. Some cases may involve only reading or writing files, but sometimes more complex tasks are at hand. Maybe you need to list all files of a given type in a directory, find the parent directory […]

Few words on Natural Language Processing and User Autonomy

As natural language processing (NLP) finds its way from university labs and becomes a crucial element of many user-facing technologies (machine translation, search, language-model-based assistants), people start to get concerned about the ethics of this technology. When people talk about NLP ethics, the main topics are: biases that the models get from training data, replication of toxic behavior found on the Internet, underrepresentation of already underprivileged groups, differences between the technology availability between the global north and global south. Now, […]

Using OrderedDict in Python

Sometimes you need a Python dictionary that remembers the order of its items. In the past, you had only one tool for solving this specific problem: Python’s OrderedDict. It’s a dictionary subclass specially designed to remember the order of items, which is defined by the insertion order of keys. This changed in Python 3.6. The built-in dict class now keeps its items ordered as well. Because of that, many in the Python community now wonder if OrderedDict is still useful. […]

Polars for initial data analysis, Polars for production

Initial data analysis (IDA) has different goals than your final, production data analysis: With IDA you need to examine the initial data and intermediate results, check your assumptions, and try different approaches. Exploratory data analysis has similar requirements. Once you’re happy with your approach, and you’re ready to run the analysis in an automated manner, you care a lot more about speed and resource usage. These different goals often benefit from different implementation strategies and tools—unless you have a sufficiently […]
