When developing code, it is not only important to consider its functionality, but also its readability. This is especially important in working environments where a team of people are working on the same code. Readable code that is unified by…
When there is a need to explore data or generate visualizations related to geographic entities (the polygon of a country or geographic coordinate points) it is quite reasonable to think about maps. Sometimes it may be valid to use simpler…
Today we are going to talk about two ways of testing in Apache Airflow. Historically, testing in Airflow has been something that has been a headache for all users of the famous framework. The coupling of the code with the…
PyCharm is an IDE developed by JetBrains for Python. As an IDE, its goal is to provide the programmer with a set of features that make code development in this language more efficient. For example, it automatically writes import lines…
Function overloading is a very interesting tool that allows several different functions to share the same identifier. This makes the readability and interpretability of our code better in some scenarios. This tool is available by default in many of today’s…
Modeling and explaining the consumer behavior of a product is very important to know what factors affect their behavior, price being one of these important factors. Let’s take as an example a company X that sells clothing. It is a…
What is software testing? Software tests are tests that are performed on a piece of code or an entire software to validate that the behavior of the software is as expected. The main purpose of testing is to detect errors…
What is a linear regression? A linear regression is a model that is used to approximate the linear relationship between a dependent variable Y and a set of independent variables X. In matrix format it can be expressed as where…
In this post we are going to talk about how DBT integrates with Spark and how this integration can be useful for us. DBT is a framework that facilitates the design of data modeling throughout the different data modeling cycles.…
In a previous post, we analyzed from a theoretical point of view which are the main libraries for data science and machine learning used by data scientists to treat data efficiently and extract its full potential. In this post, we…
