Byte
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...

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...

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(...
In Java, or even many other languages, you may have run into an error like "index 0 out of bounds for length 0". Especially for beginners, this might seem like a confusing error, given that you know array indexes start at 0. This error actually occurs when your...

The string.replace() method is a convenient way of changing an recurring expression inside a string to another expression - in other words, to replace all occurrences of a string within another string. The notation is: modified_string = my_string.replace('text_I_want_to_change', 'new_...
