What Is Virtualenv?

Virtualenv is a tool that creates an isolated environment separate from other projects. In this instance, we will be installing different Python versions, including their dependencies.  Creating a virtual environment allows us to work on a Python project without affecting other projects that also use Python. It will utilize Python's core files on the global environment to run, thus saving you disk space while providing the freedom to use different Python versions for separate apps or projects.

Artificial intelligence (AI) is a term to describe a branch of computer science that is dedicated to creating intelligent machines that would learn to work and react like humans. The field of Artificial Intelligence is not limited to creating only high levels of machine learning, but also to utilize data input in a manner required to produce a needed result. AI has multiple varieties and characteristics. Some of these types are noted as follows.

What is PyCharm?

PyCharm is an IDE (or Integrated Development Environment) for the Python programming language. It is a cross-platform development environment that is compatible with Windows, macOS, and Linux. It provides a tool that integrates code analysis, graphical debugging, unit testing, and also contains an integrated terminal that supports development on remote hosts and virtual machines.

Arguably one of the easiest tools to use for installing and managing Python packages, Pip has earned its notoriety by the number of applications utilizing this tool. Fancied for its capabilities in handling binary packages over the easy_installed packages manager, Pip enables 3rd party package installations. Though Python does sometimes come with Pip as a default, this tutorial will show how to install, check its version as well as some basic commands for using Pip on Ubuntu 16.04.

What is SaltStack?

SaltStack is an open-source infrastructure management platform built on a dynamic communications bus. The main structure of SaltStack contains two main components for work: one Salt Master and several Salt Minions. Salt Master is the main control system used to send commands to Salt Minion and their configuration. Salt Minions (they are also called Nodes) are subsystems that work on managed servers and receive commands from the master, as well as their configuration. At least two servers are required for interaction settings. One for the Master and one for the node. All nodes are configured in the same way.

Keras is a Python-based high-level neural networks API that is capable of running on top TensorFlow, CNTK, or Theano frameworks used for machine learning. It can be said that Keras acts as the Python Deep Learning Library. Keras was created with emphasis on being user-friendly since the main principle behind it is “designed for human beings, not machines.” The core data structure of Keras is a model, or a way to organize layers.

In this tutorial, we will consider how to enable both Python 2 and Python 3 for use on CentOS 8. In earlier distributions of CentOS, an unversioned Python command was available by default. 

Today, we have multiple tools at our disposal when it comes to web application testing. Sometimes, it can be challenging to make the right decision when it comes to choosing a web application testing tool that fits your specific needs. There are endless factors that come into play when inspecting, verifying, and assessing code as multiple factors come into play that depends on the type of platform being used (e.g. a server cluster or virtual cloud-based system), the programming language being employed as well as the purpose of the web application itself.

Python is a general-purpose programming language designed for various uses. For example, websites, industrial robotics, and even games all use the same core technology.

The SQLAlchemy Toolkit and Object Relational Mapper is an extensive set of utilities for working with Python and databases. This toolkit provides a package full of popular persistence patterns, designed for economical and robust database accessibility. SQLAlchemy allows a developer to use simple SQL statements (unlike other Object Relational Mapping tools) which provide a helpful method to connect database tables with user-defined Python classes. The SQLAlchemy Object Relational Mapping tool is primarily centered on using the SQL Expression language.
