Byte
Regular Expressions are widely-applicable and used to match patterns in text, whether for search, validation or other processing. A common way to use them is to check whether a number is valid - i.e. follows a pattern. IP addresses follow a particular pattern, and can be tested with Regular...

In this short Byte - we'll take a look at how you can collect and turn a list into a singleton set in Java, using the Functional API, and paired with the collectingAndThen() collector. Advice: If you'd like to read more about collectingAndThen() - read our in-depth "Guide to...

Tree-based models have become a popular choice for Machine Learning, not only due to their results, and the need for fewer transformations when working with data (due to robustness to input and scale invariance), but also because there is a way to take a peek inside of them to see...

NumPy (oftentimes also written as Numpy) is a linear algebra library, which is the basis for most of the scientific computing done in Python. Most libraries for data science, analysis and machine learning are built on top of NumPy as the basis for linear algebra, and also have tight coupling...

Getting the number of elements in a list is a common operation during software development. In Java - fetching the length of a list is done via the size() method, which accesses the cached length of the list in O(1) lookup time. List<Integer> arrayList = List.of(...
Dictionaries in Python are an implementation of hash tables: a data structure on which data is labeled by a key-value. This data structure is efficient for looking up data by its key, with an expected O(1) lookup time. It is important to keep in mind that dict objects are...
